I don't know whether they're compatible.  Also there is probably nothing
to implement from mtl in monadLib, so the more natural choice is not to
use mtl at all and just use monadLib.

I'd hate to be forced to go back to mtl.  Better update 'operational' to
support monadLib.  Go forward to a good design instead of trying to keep
old, broken designs alive.
