Weak Head Normal Form. Normal form means, the expression will be fully evaluated. Whnf [ (\x.y) z ] = false (1) whnf [ \x.
STEVEN CHABEAUX Creating the Head Normal map
A term in weak head normal form is either a term in head normal form or a lambda abstraction. (f x) ] = false (2) whnf [ x y ] = whnf [ x ] (3) in all other cases whnf [x] = true (4) Whnf [ (\x.y) z ] = false (1) whnf [ \x. And once i read through them i thought i got it. Normal form means, the expression will be fully evaluated. Web reduce terms to weak normal forms only. Web lambda calculus is historically significant. Seq is defined as follows. Web 1 there are already plenty of questions about weak head normal form etc. The evaluation of the first argument of seq will only happen when the.
The evaluation of the first argument of seq will only happen when the. (f x) ] = false (2) whnf [ x y ] = whnf [ x ] (3) in all other cases whnf [x] = true (4) Normal form means, the expression will be fully evaluated. But then i read this wikipedia article where whnf is defined for the lambda calculus as follows: But more importantly, working through the theory from its original viewpoint exposes us to different ways of thinking. And once i read through them i thought i got it. Web 1 there are already plenty of questions about weak head normal form etc. Reduction strategies [ edit ] Web weak head normal form. Web weak head normal form. Web the first argument of seq is not guaranteed to be evaluated before the second argument.
