extensible-effects is also based on freer monads. One advantage over 
freer-simple and other libraries is that it includes monad-control 
instances for most used effects, allowing to mostly painlessly use 
things like forkIO. The limitations of monad-control apply though.

Huge disclaimer: I'm one of the contributors to extensible-effects.
