Simple higher order function for Maybe

Latest on Hackage:0.1.0.0

This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.

Maybe you just need justify?

We've all used Maybe in a control flow

if f x then Just x else Nothing

but why not have

justify id f x

multiple constraints?

justify id (\a -> f a && g a) x

want a silly id for Maybe?

justify fromJust isJust (Just x)

This seems like such a no brainer that I'm surprised it isn't in Data.Maybe so I'm proposing that it should be and this library is just the start.

What about licensing issues?

Since I know there will be some talk about licensing, I already took the step and used the unlicense. If that isn't enough, just send a pull request changing it to an appropriate license and I'll accept.

What do I do while this isn't in Data.Maybe?

Then just go ahead and pull in maybe-justify from cabal!
