/***********************************************************
* Changed all copyright messages to include 1993. * Stubs for faster implementation of local variables (not yet finished) * Added function name to code object. Print it for code and function objects. THIS MAKES THE .PYC FILE FORMAT INCOMPATIBLE (the version number has changed accordingly) * Print address of self for built-in methods * New internal functions getattro and setattro (getattr/setattr with string object arg) * Replaced "dictobject" with more powerful "mappingobject" * New per-type functio tp_hash to implement arbitrary object hashing, and hashobject() to interface to it * Added built-in functions hash(v) and hasattr(v, 'name') * classobject: made some functions static that accidentally weren't; added __hash__ special instance method to implement hash() * Added proper comparison for built-in methods and functions

Additional macros for modules that implement new object types.
You must first include "object.h".
NEWOBJ(type, typeobj) allocates memory for a new object of the given
type; here 'type' must be the C structure type used to represent the
object and 'typeobj' the address of the corresponding type object.
Reference count and type pointer are filled in; the rest of the bytes of
the object are *undefined*! The resulting expression type is 'type *'.
The size of the object is actually determined by the tp_basicsize field
of the type object.
NEWVAROBJ(type, typeobj, n) is similar but allocates a variable-size
object with n extra items. The size is computer as tp_basicsize plus
n * tp_itemsize. This fills in the ob_size field as well.

extern object *newobject PROTO((typeobject *));
extern varobject *newvarobject PROTO((typeobject *, unsigned int));
#define NEWOBJ(type, typeobj) ((type *) newobject(typeobj))
#define NEWVAROBJ(type, typeobj, n) ((type *) newvarobject(typeobj, n))
