Something that I have been wondering for a while is: why are there
*still* two monad transformer libraries with seemingly identical
functionality, especially given that they have conflicting
namespaces? It creates stupid problems like the one that Erik
encountered and had to work around.
I recognize that this situation most likely came about via historical
accident rather than by intention, but why does it continue to be true?
