[dependabot-preview]

Bumps astroid from 2.0.4 to 2.2.3.

Changelog

Sourced from astroid's changelog.

What's New in astroid 2.2.3?

Release Date: 2019-03-03

• Replace any with uninferable when returning values from numpy transform

  Turns out that this was conflicting with the any builtin, while the original
  intention was to return a value that cannot be inferred, until we have support
  for types.

  This should fix a couple of false positives on pylint's side where the return
  value of numpy functions was considered to be itself a function.

  Close numpy comparison-with-callable / no-member confusion pylint-dev/pylint#2784

What's New in astroid 2.2.2?

Release Date: 2019-03-02

• Generated proper environment markers for installing typed-ast.

What's New in astroid 2.2.1?

Release Date: 2019-03-02

• Make sure to infer the arguments to the slice() builtin

Close pylint-dev/pylint#2770

• Correctly instantiate exception instances when inferring their attributes with objectmodel

Close pylint-dev/pylint#2776

What's New in astroid 2.2.0?

Release Date: 2019-02-27

• Fix a bug concerning inference of calls to numpy function that should not return Tuple or List instances.

Close pylint-dev/pylint#2436

• typed_ast gets installed for Python 3.7, meaning type comments can now work on 3.7.

• Fix a bug concerning inference of unary operators on numpy types.

  Close False positive E1130 invalid-unary-operand-type for Numpy array pylint-dev/pylint#2436 (first part)

• Fix a crash with typing.NamedTuple and empty fields. Close "invalid syntax" on typing.NamedTuple pylint-dev/pylint#2745
