Perhaps func.__signature__ should be a computed the first time it is accessed?
The PEP already declares that signatures are lazily generated. signature() checks to see if __signature__ is set, and if it is returns it. (Or, rather, a deepcopy of it, assuming we go down that route.) If __signature__ isn't set, signature() computes it and returns that. (Possibly caching in __signature__, possibly not, possibly caching the result then returning a deepcopy.)
