Catch function signature inspection errors for built-in types

bfrascher · sebastinas · commit cd6886a5b1ea · 2019-04-02T22:19:09.000+02:00
Some built-in functions (e.g. `map`) can't be inspected with
`inspect.getargspec`, `inspect.getfullargspec` or `inspect.signature`.  The
exceptions from `inspect.getargspec` and `inspect.getfullargspec` are all caught
in the code, but `inspect.signature` raises a `ValueError` instead of a
`TypeError`.  This exception is now also caught.
