1e99a77120 Various sundry changes for 2.2 compatibility
Remove the option to have nested scopes or old LGB scopes.  This has a
large impact on the code base, by removing the need for two variants
of each CodeGenerator.

Add a get_module() method to CodeGenerator objects, used to get the
future features for the current module.

Set CO_GENERATOR, CO_GENERATOR_ALLOWED, and CO_FUTURE_DIVISION flags
as appropriate.

Attempt to fix the value of nlocals in newCodeObject(), assuming that
nlocals is 0 if CO_NEWLOCALS is not defined.

652a22437a The object-being sliced in an assignment to a slice is referenced, not
bound.

When a Yield() node is visited, assign to the generator attribute of
the scope, not the visitor.

a0ca3d611e - Reverse the meaning of the -m option: warnings about multiple /
operators per line or statement are now on by default, and -m turns
  these warnings off.

- Change the way multiple / operators are reported; a regular
  recommendation is always emitted after the warning.

- Report ambiguous warnings (both int|long and float|complex used for
  the same operator).

- Update the doc string again to clarify all this and describe the
  possible messages more precisely.

13c51ecb8c Added more text to the docstring, updated the way the exit status is
percolated out, and some general cleanup.  The output is still the
same, except it now prints "Index: <file>" instead of "Processing:
<file>", so that the output can be used as input for patch (but only
the diff-style parts of it).

e4685ec57e Track the block stack more reasonably in order to handle continue in
try/except or try/finally.

Previous versions had only track SETUP_LOOP blocks and ignored the
exception part.  This meant that it allowed continue inside a
try/except but generated buggy code.  Now it does the right thing.

bf77c465bd Undo change from list to dict for handling varnames, consts, etc.
As the doc string for _lookupName() explains:

    This routine uses a list instead of a dictionary, because a
    dictionary can't store two different keys if the keys have the
    same value but different types, e.g. 2 and 2L.  The compiler
    must treat these two separately, so it does an explicit type
    comparison before comparing the values.

7abf520d6c Add support for // and //=.
Avoid if/elif/elif/else tests where the final else is supposed to
handle exactly one case instead of all other cases.  When the list of
operators is extended, the catchall else treats all new operators as
the last operator in the set of tests.  Instead, raise an exception if
an unexpected operator occurs.

e4e9cd4c01 Modify name conversion to be (hopefully) a bit more efficient.
Use a dictionary instead of a list to map objects to their offsets in
a const/name tuple of a code object.

XXX The conversion is perhaps incomplete, in that we shouldn't have to
do the list2dict to start.

5477f529d6 Revise implementations of getChildren() and getChildNodes().
Add support for floor division (// and //=)

The implementation of getChildren() and getChildNodes() is intended to
be faster, because it avoids calling flatten() on every return value.
But it's not clear that it is a lot faster, because constructing a
tuple with just the right values ends up being slow.  (Too many
attribute lookups probably.)

The ast.txt file is much more complicated, with funny characters at
the ends of names (*, &, !) to indicate the types of each child node.

The astgen script is also much more complex, making me wonder if it's
still useful.

c59e220000 Handle private names
(Hard to believe these were never handled before)

Add misc.mangle() that mangles based on the rules in compile.c.
XXX Need to test the corner cases

Update CodeGenerator with a class_name attribute bound to None.  If a
particular instance is created within a class scope, the instance's
class_name is bound to that class's name.

Add mangle() method to CodeGenerator that mangles if the class_name
has a class_name in it.

Modify the FunctionCodeGenerator family to handle an extra argument--
the class_name.

Wrap all name ops and attrnames in calls to self.mangle()

2afff324ea Many changes -- bug fixes and sundry improvements
Make nested scopes enabled by default

Add is_constant_false() helper so that compiled code and symbols are
consistent with builtin compiler's handling of "if 0:"

Fix doc string handling to be consistent with recent change that
eliminates the doc string from the Module's node attribute.

Add fix to print handling from Evan & Shane.

Track change to visitor api by making "verbose" explicit.

Comment out setting CO_NESTED flag (it's unnecessary in 2.2).

cd8a127e1a Fix for sibling nodes that define the same free variable
Evan Simpson's fix.  And his explanation:

    If you defined two nested functions in a row that refer to the
    same non-global variable, the second one will be generated as
    though the variable were global.

7e30c9bb5a Add lookup_name() to optimize use of stack frames
The use of com_node() introduces a lot of extra stack frames, enough
to cause a stack overflow compiling test.test_parser with the standard
interpreter recursionlimit.  The com_node() is a convenience function
that hides the dispatch details, but comes at a very high cost.  It is
more efficient to dispatch directly in the callers.  In these cases,
use lookup_node() and call the dispatched node directly.

Also handle yield_stmt in a way that will work with Python 2.1
(suggested by Shane Hathaway)

e47e97792a Implement some suggestions by Laura Creighton.
ChipWidget.__init__(): Added a message area just below the color
    name.  Both the message and name widgets are now FLAT, DISABLED
    Entry widgets instead of Labels.  This allows users to
    copy-n-paste the color names or color specs.  Also, the contents
    of both widgets are now driven by StringVars.

set_color(): This only sets the chip color; it does not set the name
    widgets.

set_name(): New method which only sets the name widget contents.

set_message(): New method which only sets the message widget contents.

ChipViewer.update_yourself(): Set the color, name, and message for
    each chip as follows: the first line always contains the color
    spec in #rrggbb format.  The second line will contain the color
    name, but slightly differently for each widget.  For the Selected
    widget, if the color exactly matches the Nearest color, the name
    is shown, otherwise the message field will be empty.  The name
    field of the Nearest widget will always contain the color name.
