/// ## Why is this bad?

from ty_extensions import Unknown, is_assignable_to

@overload
def join(self, iterable: Iterable[LiteralString], /) -> LiteralString: ...
@overload

from module import Foo
from typing_extensions import LiteralString
def f(a: Foo, b: list[str], c: list[LiteralString], e):
reveal_type(e) # revealed: Unknown
# TODO: we should select the second overload here and reveal `str`
# (the incorrect result is due to missing logic in protocol subtyping/assignability)
reveal_type(a.join(b)) # revealed: LiteralString
reveal_type(a.join(c)) # revealed: LiteralString
# since both overloads match and they have return types that are not equivalent,
# step (5) of the overload evaluation algorithm says we must evaluate the result of the
# call as `Unknown`.
#
# Note: although the spec does not state as such (since intersections in general are not
# specified currently), `(str | LiteralString) & Unknown` might also be a reasonable type
# here (the union of all overload returns, intersected with `Unknown`) -- here that would
# simplify to `str & Unknown`.

Similar to the way that `typing.is_protocol` returns `False` at runtime for all generic aliases,
`typing.get_protocol_members` raises an exception at runtime if you pass it a generic alias, so we
do not implement any special handling for generic aliases passed to the function.
`ty_extensions.reveal_protocol_interface` can be used on both, however:
