[Haskell-cafe] Combining computations

[michael rice]

I posted something similar about an hour ago but it seems to have gotten lost. Very strange.

I've read that Monads can combine computations. Can a Maybe monad be combined with a List monad such that

Nothing `mplus` [] ==> [] 
Just 1 `mplus` [] ==> [1]

If not, can someone supply a simple example of combining computations?

Michael
