MaybeT (m :: Type -> Type) aghc GHC.Data.Maybe 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.

ghc GHC.Data.Unboxed Like Maybe, but using unboxed sums. Use with care. Using a unboxed maybe is not always a win in execution *time* even when allocations go down. So make sure to benchmark for execution time as well. If the difference in *runtime* for the compiler is too small to measure it's likely better to use a regular Maybe instead. This is since it causes more function arguments to be passed, and potentially more variables to be captured by closures increasing closure size.
