compiler AST

[Phil Frost]

The first comment in the source is not the docstring; iff the first
statement in the module is a string, this is the docstring. Comments are
delimited by # and \n. Strings are in quotes.

AST does not parse comments, but it does parse docstrings. There are
available in the .doc attribute of nodes that can have them.
