A monad and monad transformer for pushing things onto a stack very fast. https://github.com/wyager/FastPush/

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.
This library gives you a monad that lets you push things onto a stack very quickly. You get things off the stack when you run the monad. Under the hood, this uses mutable vectors. I've also included a monad transformer using the STMonadTrans library that does the same thing as a transformer, but it's probably very unsafe.
