(Code contributed by Jiwon Seo.) The documentation portion of the patch is being re-worked and will be checked-in soon. Likewise, PEP 289 will be updated to reflect Guido's rationale for the design decisions on binding behavior (as described in in his patch comments and in discussions on python-dev). The test file, test_genexps.py, is written in doctest format and is meant to exercise all aspects of the the patch. Further additions are welcome from everyone. Please stress test this new feature as much as possible before the alpha release.

# This file describes the nodes of the AST in ast.py. The module is

# generated by astgen.py.
|
|
# The descriptions use the following special notation to describe
|
|
# properties of the children:
|
|
# * this child is not a node
|
|
# ! this child is a sequence that contains nodes in it
|
|
# & this child may be set to None
|
|
# = ... a default value for the node constructor (optional args)
