'inspect.signature' currently returns 'None' for builtins with no signature information. However, the protocol is that it raises a "ValueError(callable is not supported by signature)" if object is callable, but a signature can not be provided. Attached patch fixes this, as well as updates the relevant section in the inspect.signature documentation.

This is already a part of (except the doc fix).

I see. Could you please incorporate the doc change and unittests into the patch for #20189?

If you want to make sure that happens, please review my next patch for #20189, or fix it after that patch goes in if I forget. (Honestly it's hard for me to keep track of everything right now.)

I've worked your changes into the patch for #20189.
