A custom AST hierarchy for our own use #9

The default python AST objects are clunky and annoying:

They don't have nice __str__s or __repr__s
They don't have a constructor that will work with pattern matching
They don't have structural equality
Behave differently in CPython, PyPy and Jython and are probably the main reason why Jython doesn't work right now.

In general they are a pain to use. It would be great if we could have a different ast representation, either using astng or made ourselves using case classes.

Can you direct me to where we're using or parsing the AST?

thedrow commented 9 years ago

Astroid doesn't parse generators yet. See https://bitbucket.org/logilab/astroid/issue/94/add-an-infer_call_result-method-for

I don't understand how the absence of infer_call_result has any relevance to MacroPy, it looks like it's there for checking function return/call sign signatures for Pylint.
