Weak Head Normal Form
Weak Head Normal Form - Now, i have following expression: So, seq forced the list to be evaluated but not the components that make. Therefore, every normal form expression is also in weak head normal form, though the opposite does not hold in general. Web there is also the notion of weak head normal form: Weak head normal form means, the expression will only evaluate as far as necessary to reach to a data constructor. Web reduce terms to weak normal forms only. Web the first argument of seq is not guaranteed to be evaluated before the second argument. Reduction strategies [ edit ] Section 6 de ne these normal forms. Web lambda calculus is historically significant.
An expression is in weak head normal form (whnf), if it is either: Section 6 de ne these normal forms. So, seq forced the list to be evaluated but not the components that make. This means a redex may appear inside a lambda body. A constructor (eventually applied to arguments) like true, just (square 42) or (:) 1. (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). But then i read this wikipedia article where whnf is defined for the lambda calculus as follows: Aside from a healthy mental workout, we find lambda calculus is sometimes superior: Web weak head normal form.
