In a predicative type system (also known as a prenex polymorphic system), type variables may not be instantiated with polymorphic types. Predicative type theories include Martin-Löf type theory and NuPRL.

This restriction makes the distinction between polymorphic and non-polymorphic types very important; thus in predicative systems po… WebGo to Google Trends and type in any phrase related to your content.
