Add support for always tokenizing async/await as keywords
Fixes #593

I looked into this bug with @ambv and @carljm, and we reached the
conclusion was that it's not possible for the tokenizer to determine if
async/await is a keyword inside all possible generators without breaking
the grammar for older versions of Python.

Instead, we introduce a new tokenizer mode for Python 3.7+ that will
cause all async/await instances to get parsed as a reserved keyword,
which should fix async/await inside generators.

README Changes default logger used by blib2to3 Driver (#732) 2019-03-14 13:39:42 +01:00

A subset of lib2to3 taken from Python 3.7.0b2.
Commit hash: 9c17e3a1987004b8bcfbe423953aad84493a7984

Reasons for forking:
- consistent handling of f-strings for users of Python < 3.6.2
- backport of BPO-33064 that fixes parsing files with trailing commas after
  *args and **kwargs
- backport of GH-6143 that restores the ability to reformat legacy usage of
  `async`
- support all types of string literals
- better ability to debug (better reprs)
- INDENT and DEDENT don't hold whitespace and comment prefixes
- ability to Cythonize

Change Log:
- Changes default logger used by Driver
