 - f-strings are now parsed as a part of the normal Python grammar. This makes
it way easier to deal with them.

Parso is a Python parser that supports error recovery and round-trip
parsing for different Python versions (in multiple Python versions).
Parso is also able to list multiple syntax errors in your python file.

Parso has been battle-tested by jedi. It was pulled out of jedi to be
useful for other projects as well.

Parso consists of a small API to parse Python and analyse the syntax tree.
