splitVarSummands :: Type -> [(TVar, Type)]

All ways to split a type in the form: a + t1, where a is a variable.

splitVarSummand :: TVar -> Type -> Maybe Type

Check if we can express a type in the form: a + t1.

splitConstSummand :: Type -> Maybe (Integer, Type)

Check if we can express a type in the form: k + t1, where k is a constant > 0. This assumes that the type has been simplified already, so that constants are floated to the left.

splitConstFactor :: Type -> Maybe (Integer, Type)

Check if we can express a type in the form: k * t1, where k is a constant > 1. This assumes that the type has been simplified already, so that constants are floated to the left.
