For someone who doesn’t generally monkey-patch things, what motivated you
to make this library? Could you post a use-case? Looking at your example,
how does your library differ from this?
def whoAmI(self):
print("My name is %s" % [self.name](http://self.name/)())
OpenMaya.MFnTransform.whoAmI = whoAmI
On another note, you’ve got a well executed readthedocs page and your
docstrings are very well formatted. It’s quite a joy to read.
