Contrary to what lib3to6 reports, the inspect module is available on Py3.5

It's even available on python2.7.

I can't remember what my thinking was. I may have taken the statement from the inspect2 module. https://pypi.org/project/inspect2/

A backport of the Python 3.6 inspect module to Python 2.7-3.5.

In other words, if you use inspect2 then you can be sure on 2.7 - 3.5 that the semantics are the same going forward.
