Hi,

I’m in a position, where I’d like to be able to pass a reference to a Protocol Class, however, I can’t find a way to describe that variable with the current type system, as Type[ProtocolClass] means a class implementing said protocol, where I want the protocol itself, while ProtocolClass means an instance of a class implementing the protocol.

So I haven’t figured out if PEP 544 specifies a type that describes the Protocol class itself, rather than just its compatible implementations.

I tried to file this as a mypy bug, but no response yet, and alas, figure it may even be overlooked by the PEP in question.

Anyway, I’d very much appreciate a few more eyes and input on this matter.

Thank you,
Cheers
