[Python-Dev] AST structure and maintenance branches

[Anthony Baxter]

I'd like to propose that the AST format returned by passing PyCF_ONLY_AST to 
compile() get the same guarantee in maintenance branches as the bytecode 
format - that is, unless it's absolutely necessary, we'll keep it the same. 
Otherwise anyone trying to write tools to manipulate the AST is in for a 
massive world of hurt.

Anyone have any problems with this, or can it be added to PEP 6?
