@Paul, could you clarify what you mean? An example would be helpful.Do you want to pass a ParamSpec object as an argument to the callable, treating it like a runtime object rather than a special form? If so, then you'd annotate it as `(ParamSpec) -> None`. Is that what you mean?-Eric_______________________________________________Typing-sig mailing list -- typing-sig@python.orgTo unsubscribe send an email to typing-sig-leave@python.orgMember address: pbryan@anode.ca
