newtype MaybeT (m :: * -> *) a :: (* -> *) -> * -> * #

The parameterizable maybe monad, obtained by composing an arbitrary monad with the Maybe monad.

Computations are actions that may produce a value or exit.

The return function yields a computation that produces that value, while >>= sequences two subcomputations, exiting if either computation does.

Fields runMaybeT :: m (Maybe a)
