Feature Request: version of bind that preserves signature

[juan-carlos-calvo]

bind's signature after binding a function is <Signature (*args, **kwargs)> . Could it be possible to please have a version of it that gives back a function (or bind object) with the right signature after binding? for example:
for def foo(a: int, b: str, c: float, d: str='hey'): pass
its signature is <Signature (a: int, b: str, c: float, d: str = 'hey')>
and if I define bf = bind(foo, 1, _Arg(0), 2)
I would like to have bfs signature be <Signature (b: str, d: str = 'hey')>
