I agree, that we shouldn't make 'functools' be dependent on 'inspect' module. Moreover, this is not even currently possible, as it creates an import-loop that is hard to untie. But how about the following: 1. Separate 'Signature' object from 'inspect' module, and move it to a private 'signature.py' (that will depend only on 'collections.OrderedDict', 'itertools.chain' and 'types') 2. Publish it in the 'inspect' module 3. Make 'signature' method to work with any callable 4. Make 'Signature' class to accept only functions 5. Import 'signature' in the 'functools', and use 'Signature' class directly, as it will accept just plain functions. Would this work?

Sounds like a good plan to me.

Cheers, Nick.
