haskell Is the expression (_, 'b') in Normal Form? in Weak Head
Weak Head Normal Form. Web reduce terms to weak normal forms only. An expression in weak head normal form has been evaluated to the outermost data constructor or lambda abstraction (the head).
haskell Is the expression (_, 'b') in Normal Form? in Weak Head
A constructor (eventually applied to arguments) like true, just (square 42) or (:) 1. And once i read through them i thought i got it. An expression in weak head normal form has been evaluated to the outermost data constructor or lambda abstraction (the head). Section 6 de ne these normal forms. Therefore, every normal form expression is also in weak head normal form, though the opposite does not hold in general. The evaluation of the first argument of seq will only happen when the. But then i read this wikipedia article where whnf is defined for the lambda calculus as follows: Web lambda calculus is historically significant. Alonzo church was alan turing’s doctoral advisor, and his lambda calculus predates turing machines. An expression is in weak head normal form (whnf), if it is either:
Web reduce terms to weak normal forms only. But then i read this wikipedia article where whnf is defined for the lambda calculus as follows: Seq is defined as follows. Web weak head normal form. The evaluation of the first argument of seq will only happen when the. And once i read through them i thought i got it. An expression in weak head normal form has been evaluated to the outermost data constructor or lambda abstraction (the head). The first argument of seq will only be evaluated to weak head normal form. Normal form means, the expression will be fully evaluated. Alonzo church was alan turing’s doctoral advisor, and his lambda calculus predates turing machines. Aside from a healthy mental workout, we find lambda calculus is sometimes superior:
