Another option would be to directly compare the methods against known ones:

obj = func.self if isinstance(obj, np.ufunc): if func is obj.reduce: got_reduction()

For C classes like the ufuncs, it seems _self_ is defined for methods as well (at least, np.add.reduce._self_ gives np.add), but not a _func_. There is a _name_ (="reduce"), though, which means that I think one can still retrieve what is needed (obviously, this also means _arrayufunc_ could have been simpler...)

Good point! I guess this means we should encourage using name rather than func. I would not want to preclude refactoring classes from Python to C/Cython.
