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: gotreduction() I'm not quite sure why, but this doesn't seem to work with current ufunc objects:

np.add.reduce == np.add.reduce # OK True

np.add.reduce is np.add.reduce # what?!? False

Maybe this is a bug?
