Re-exports from Prim.Ordering

#LT

data LT :: Ordering

The 'less than' ordering type.

#GT

data GT :: Ordering

The 'greater than' ordering type.

#EQ

data EQ :: Ordering

The 'equal to' ordering type.

#Ordering

kind Ordering

The Ordering kind represents the three possibilites of comparing two types of the same kind: LT (less than), EQ (equal to), and GT (greater than).
