  Description     : use flake8 to catch functions with mutable default arguments

  Python's default arguments are evaluated at definition as opposed to when the
  function is invoked. This leads to unexpected behavior, as mutations persist
  between calls. This flake8 extension will warn for this type of mistake.
 
I plan to maintain this package as part of the Python team.
