Comment (by SimonKing):
Here is our problem:
{{{
sage: obj = UniqueRepresentation.__classcall__.f
sage: from sage.misc.sageinspect import sage_getsource,
_sage_getargspec_from_ast, _sage_getargspec_cython
sage: source = sage_getsource(obj, is_binary=True)
sage: _sage_getargspec_cython(source) # wrong
(['cls', '*args', '**options'], None, None, None)
sage: _sage_getargspec_from_ast(source) # correct
ArgSpec(args=['cls'], varargs='args', keywords='options', defaults=None)
}}}
Perhaps `_sage_getargspec_cython` (which is called if it is suspected that
the function is defined in Cython) should first check whether
`_sage_getargspec_from_ast` works.
