Fcf.Data.Bool

Booleans.

Note that the operations from this module conflict with Data.Type.Bool.

Documentation

data UnBool :: Exp a -> Exp a -> Bool -> Exp a

N.B.: The order of the two branches is the opposite of "if": UnBool ifFalse ifTrue bool.

This mirrors the default order of constructors:

data Bool = False | True
----------- False < True
