Message 281283 - Python tracker
There's special syntax to handle aliases. From comments in clinic.py:
# alternatively:
# modulename.fnname [as c_basename] = modulename.existing_fn_name
# clones the parameters and return converter from that
# function. you can't modify them. you must enter a
# new docstring.
Sorry the docs are out of date--patches welcome. And speaking of patches, thanks for the patch! I'll review it when you say it's ready.
