public abstract class StrictFunction3
extends jfun.jaskell.AbstractFunction3

extend this class to provide a strict function implementation. Subclassing this class is more efficient than calling addStrictFunction.
A strict function is a function whose arguments are evaluated before the function body is evaluated.
