The GHCi Monad lifting interface.
EXPERIMENTAL! DON'T USE.
The API of this module is unstable and not meant to be consumed by the general public.
If you absolutely must depend on it, make sure to use a tight upper
bound, e.g., base < 4.X
rather than base < 5
, because the interface can
change rapidly without much warning.

A monad that can execute GHCi statements by lifting them out of m into the IO monad. (e.g state monads)
