type Constraint = CONSTRAINT LiftedRep Source #
The kind of lifted constraints
The builtin function type, written in infix form as a % m -> b
.
Values of this type are functions taking inputs of type a
and
producing outputs of type b
. The multiplicity of the input is
m
.
Note that
permits representation polymorphism in both
FUN
m a ba
and b
, so that types like
can still be
well-kinded.Int#
