I would like to know how much the AST have been changed on moving from python2.4 to python 2.5 so that I can bring the corresponding changes in Zope2 to get it adapted to those changes in the AST.
Notice that Parser/Python.asdl is new in Python 2.5, so (by today's terminology) Python 2.4 did not really have any AST. The relevant NEWS entry is
- A new AST parser implementation was completed. The abstract syntax tree is available for read-only (non-compile) access to Python code; an _ast module was added.
Python's prior notion of abstract syntax (which is rather a CST) directly reflects from the grammar; do
svn log Grammar/Grammar
to find out what exactly was changed.
Regards, Martin
