Add argcount to the function wrappers #215

Closed DeviousStoat closed 5 months ago

DeviousStoat commented 5 months ago

fixes #210

since we do not know in advance what the function will be in the functon wrappers, the __call__ method is usually defined with the (*args, **kwargs) signature. however at runtime, when the wrapper is instanciated we know what the wrapped function is and we can return an argcount in most cases.

This PR adds the _argcount value to the function wrapper when possible, simply returning the argcount of the wrapped function when appropriate or with a few adjustments when needed. This way they can be used nicely with other functions that takes predicate like in the example in the issue linked above.
