This is probably a failure of my search fu or some other mental

somewhere:

\a b -> runKleisli $ (Kleisli a) <+> Kleisli b

Not a single name, but I believe
liftA2 mplus
is the same function, and much shorter (and more general).
That’s the ticket. I was sure there was something like that (and
I almost asked if there was a library function g such that g
mplus = …).

Thanks,
