Summary0000571: Improve unsatisfiable typeclass constraint errors
DescriptionThe attached program generates the following error messages:

    unsat_error.m:015: In clause for predicate `create_schedule'/3:
    unsat_error.m:015: unsatisfiable typeclass constraint:
    unsat_error.m:015: `unsat_error.logger(L)'.

For cases like this it would better if we could provide the user some indication of the cause of this constraint being unsatisfiable, namely that the there is no constraint on the type variable Logger in the predicate declaration.
