What's wrong
When using returns.curry.partial, if you partially apply a positional parameter using a keyword argument, the resulting type is incorrect. Result type of callable allows passing the remaining arguments as positional, but this leads to a runtime error.
Example
def foo(x: int, y: int) -> None:
...
bar = returns.curry.partial(foo, x=1)
reveal_type(bar)
# => Mypy: "def (y: builtins.int)"
# => Expected: "def (*, y: builtins.int)"
bar(2)
# No errors from mypy, but got runtime error
# TypeError: foo() got multiple values for argument 'x'How is that should be
In this scenario, the remaining parameters should be strictly keyword-only. The resulting type should reflect this restriction, and passing a positional argument should be flagged as an error at type checking time.
