No support for async/await (updated title)

[takeda]

When trying to check the code that was indented with tabs it spews errors like this:

test.py:8: error: Parse error before "def"
test.py:8: error: Parse error before :
test.py:9: error: Inconsistent indentation
test.py:10: error: Parse error before "p"

It's a bug, but IMO not a very important one (I haven't encountered tab-indented code in years). However, maybe it's easy to fix? The place to fix would be mypy/lex.py. Do you feel like sending a pull request?

Sure, will do.

Well... this is embarrassing. The tabs actually do work fine, what I run into was #913. The code I was checking utilized async/await statements.

No problem! At least now you know our issue tracker works. :-)
