Indeed. Argument handling is certainly a tricky one - getting positional only arguments requires a bit of a hack in pure Python code (accepting *args and unpacking the arguments manually), but it comes reasonably naturally when parsing arguments directly using the C API. As another example where these questions will arise (this time going the other way) is that I would like to see a pure-Python version of partial added back in to functools, with the C version becoming an accelerated override for it.
