enhanced_partial()

Enhanced partial application with _argcount tracking.

Implementation

Args: func: The function to partially apply *bound_args: Arguments to bind **bound_kwargs: Keyword arguments to bind Returns: A partially applied function with _argcount metadata

Example

                            def multiply(a, b, c):
    return a * b * c
times_two = enhanced_partial(multiply, 2)
times_two(3, 4)
                        

Expected output: 24
