Agreed this is python-ideas territory, but yes there's definitely
interest in being able to mark a section of code as being compiled to
an AST object at compile time, and then further processed at runtime
(essentially having syntax to switch on PyCF_ONLY_AST for a
subexpression and/or entire statement).

At the moment, you can do this all through the ast module and the
PyCF_ONLY_AST flag to compile(), but you need to pass the code to be
compiled around as strings, which tends to somewhat user (and IDE!)
unfriendly.

Cheers,
Nick.
