liftM2, liftA2

liftM2

According to Hoogle, liftM2 “lifts a function into a Monad”.

In the examples on this site, I call this a famb, which means F<A,M<B>>.

liftA2

According to Hoogle, liftA2 “lifts a function into an Action”. I guess Actions are what Actors do.

One day I will understand what this means, and I will provide a simple example in Java.
