Support Literal types #274
Description
After we have delegate in-place we can use Literal types.
But, now they are not supported.
Ideally, something like this should work:
from classes import typeclass, AssociatedType, Supports
from typing_extensions import Literal
class SomeDelegate(object):
... # TODO: write proper `__instancecheck__`
class A(AssociatedType):
...
@typeclass(A)
def some(instance) -> int:
...
@some.instance(Literal[1], delegate=SomeDelegate)
def _some_tuple(instance: Literal[1]) -> int:
return instance
def test(i: Supports[A]):
return some(i)
some(1)
