I can volunteer for 328 if no one else wants it, I've messed with the import
mechanism before (and besides, it's fun.) I've also written an unfinished
308 implementation to get myself acquainted with the AST code more.
'Unfinished' means that it works completely, except for some cases of
ambiguous syntax. I can fix that in a few days if the deadline nears and
there's no working patch.

(Naively adding if/else expressions broke list comprehensions with an 'if'
clause, and fixing that broke list comprehensions with 'for x in lambda:0,
lambda:1', and fixing that broke list comprehensions altogether... I added
"clean up Grammar file" to the PyCon core sprint topics for that reason. I
guess 308 wasn't as much a trainer implementation as people thought ;) The
syntax part of 328 is probably easier (but the rest isn't.)

If this still needs work when I finish grokking the AST code and the PyObj
branch of it, I can help.

I should have more than enough spare time to finish these things before
alpha 1.
