Weak Head Normal Form
Weak Head Normal Form - Therefore, every normal form expression is also in weak head normal form, though the opposite does not hold in general. This means a redex may appear inside a lambda body. Web reduce terms to weak normal forms only. Now, i have following expression: Web lambda calculus is historically significant. Section 6 de ne these normal forms. Seq is defined as follows. Web the first argument of seq is not guaranteed to be evaluated before the second argument. Web there is also the notion of weak head normal form: So, seq forced the list to be evaluated but not the components that make.
