Message 253475 - Python tracker

This is the situation I am in: coverage.py uses getargspec in a very simple way in its tooling.  I support 2.7 and 3.5, so I have to do this:

    try:
        getargspec = inspect.getfullargspec
    except AttributeError:
        getargspec = inspect.getargspec
    argspec = getargspec(function)

It seems like needless churn.
