[issue23653] Make inspect._empty test to False

[Yury Selivanov]

Yury Selivanov added the comment:

Nathan, consider the following signature:

  def foo(a=0:''): pass

now, sig.parameters['a'].annotation will be '' and .default will be 0, and they will fail 'if param.annotation or param.default' check.  That's why we encourage checks like 'if param.annotation is not param.empty'.

Closing this issue.
