[Python-Dev] asdl.py and Python-ast.[hc]

Hi All, Earlier this morning I had a slight tackle with a couple of the 3.4 bots (sorry everyone!). I fixed some problems in asdl.py - http://hg.python.org/cpython/rev/21d46e3ae60c - and used the 'with' statement. Some bots don't have Python 2.6+ and couldn't bootstrap Python-ast.h/c Two questions: * Should I always check-in Python-ast.h and Python-ast.c when I touch asdl* ? The generated files are unchanged, it's only the timestamp that changed. * Can we, in theory, use new Pythons for asdl* code, because Python-ast.* are, in fact, checked in so they don't have to be rebuilt by the bots or users? Thanks in advance, Eli
