inspect.signature(object) works fine in my (not yet posted) latest #20189 patch.
inspect.signature(type) doesn't work, because it's not clear what the signature for type should be. There's the one-argument and three-argument approaches. This is technically true:
"(object_or_name, [bases, dict])"
However,
a) it's painful to look at,
b) I can't communicate the idea of an "optional group" in an inspect.Signature object right now (although I guess we're going to hash that out somewhere, which is good).
If we can agree on a good signature for inspect.signature(type), I can make it happen.
