I don't think we need this logic...

@sydney-runkle
please correct me If I am wrong, but removing this logic will not support:
annotated_types.Not(annotated_types.MultipleOf(2)) or any other annotated types like Ge, Le, etc.. with Not

@aditkumar72, that's true, but the signature of Not indicates that it takes: func: Callable[[Any], bool], so I don't feel like we should support types like at.Not(Gt(2)) because that's not type safe:
Argument of type "Gt" cannot be assigned to parameter "func" of type "(Any) -> bool" in function "__init__"
Type "Gt" is incompatible with type "(Any) -> bool"

So I'm inclined to just support callables, as the signature indicates - feel free to modify the tests accordingly.

I realize this is contradictory to the initial feature request - I'd suggest that folks can design a custom Not type if they'd like to go that route.

I wonder if things could be adapted on the annotated-types side. Not(<constraint>) looks like a useful pattern

@Zac-HD, thoughts ^^?

I sketched out an idea in annotated-types/annotated-types#74 (review) but nobody's volunteered to implement it yet 🙂

@aditkumar72 let's implement support in pydantic given the existing api for Not, then we can expand it down the line.

Other than the not in the val_func, this is basically identical to the Predicate logic - can we consolidate this logic?
