Data.Singletons.Base.TypeRepTYPE

Description

This module defines singleton instances making TypeRep the singleton for the kind TYPE rep (for some RuntimeRep rep), an instantiation of which is the famous kind Type. The definitions don't fully line up with what is expected within the singletons library, so expect unusual results!

A choice of singleton for the kind TYPE rep (for some RuntimeRep rep), an instantiation of which is the famous kind Type.

Conceivably, one could generalize this instance to `Sing @k` for any kind k, and remove all other Sing instances. We don't adopt this design, however, since it is far more convenient in practice to work with explicit singleton values than TypeReps (for instance, TypeReps are more difficult to pattern match on, and require extra runtime checks).

We cannot produce explicit singleton values for everything in TYPE rep, however, since it is an open kind, so we reach for TypeRep in this one particular case.

Here is the definition of the singleton for TYPE rep:

type instance Sing \@(TYPE rep) = TypeRep
