In order to check for argument types I should either assume type
annotation (python 3 only, optional) or parse the docstring for the
method, which might not be available or be out of sync.
I just want to check for method name, number and/or names of the
arguments. It might not be trivial in python because the very same
argument can be passed either as a positional or a kw argument, so
def method1(self, a, b):
...
def method1(self, c, d):
...
could satisfy or not the very same interface, depending whether the
args are passed as postional or kw.
