These functions were undocumented and excluded from the limited C API. Most names defined by these header files were not prefixed by "Py" and so could create names conflicts. For example, Python-ast.h defined a "Yield" macro which was conflict with the "Yield" name used by the Windows <winbase.h> header. Use the Python ast module instead. * Move Include/asdl.h to Include/internal/pycore_asdl.h. * Move Include/Python-ast.h to Include/internal/pycore_ast.h. * Remove ast.h header file. * pycore_symtable.h no longer includes Python-ast.h.
