Feature or enhancement

Currently, Argument Clinic will not allow parameters namedmodule, even though they've got a custom C name. For example, this clinic input is rejected:

/*[clinic input]mod.func    module as mod: object[clinic start generated code]*/

AC complains with"You can't have two parameters named 'module'!", even though there is no naming collision on the C level. This issue prevents AC conversion of some functions and methods in the code base, for examplewarn_explicit() in Python/_warnings.c. A workaround is to provide a custom name to the self converter, however I view that as a hack; it adds unneeded clinic code.

/*[clinic input]mod.func    _module: self(type="PyObject *")    module as mod: object[clinic start generated code]*/

Pitch

The fix is easy (itsalmost a one-liner), and it unlocks more AC conversions, without requiring unneeded hacks.
