<description>
Returns a copy of this [Callable] with the arguments unbound, as defined by [param argcount]. Calling the returned [Callable] will call the method without the extra arguments that are supplied in the [Callable] on which you are calling this method.
Returns a copy of this [Callable] with a number of arguments unbound. In other words, when the new callable is called the last few arguments supplied by the user are ignored, according to [param argcount]. The remaining arguments are passed to the callable. This allows to use the original callable in a context that attempts to pass more arguments than this callable can handle, e.g. a signal with a fixed number of arguments. See also [method bind].

foo.unbind(1).call(1, 2) # Calls foo(1).
foo.bind(3, 4).unbind(1).call(1, 2) # Calls foo(1, 3, 4), note that it does not change the arguments from bind.
