This will finally allow me to just load modules importing transformers
into ghci without using "-hide-all-packages -package transformers
-package ..." or without using the package imports extension.

Just for the interested, here are all the reverse dependencies on transformers:

(Note that you can sort the columns by clicking on the column headers)

BTW is there a plan and roadmap documented somewhere on the future of mtl?
