Weak Head Normal Form
Weak Head Normal Form - This means a redex may appear inside a lambda body. A term in weak head normal form is either a term in head normal form or a lambda abstraction. Whnf [ (\x.y) z ] = false (1) whnf [ \x. Weak head normal form means, the expression will only evaluate as far as necessary to reach to a data constructor. Web weak head normal form. Reduction strategies [ edit ] (f x) ] = false (2) whnf [ x y ] = whnf [ x ] (3) in all other cases whnf [x] = true (4) An expression in weak head normal form has been evaluated to the outermost data constructor or lambda abstraction (the head). Normal form means, the expression will be fully evaluated. Seq is defined as follows.
