It's already a feature in the python stdlib through ctypes, so it obviously doesn't break the guidelines that much.
Also, it's not any less explicit.. it'd just be nice to create the mapping once on the class then have the calling convention respect that everywhere else. In many ways this is more pythonic than repeatedly typing the same 'few characters' every time i make a function call into a C library. As you said, this isn't really a special case, so many of us are doing it...
