Enum WindowKind 

pub enum WindowKind {
    Prefix,
    Suffix,
    Scan,
}

Which windowed application a Verb::Windowed performs. One variant covers all three because the work is the same: the verb is applied to a run of consecutive items, and only the choice of runs differs.

Variants

Prefix

J u\: the monad applies u to every prefix, the dyad x u\ y to every window of x items.

Suffix

J u\.: the monad applies u to every suffix; the dyad (outfix) is not implemented.

Scan

APL f\ and f⍀: the monad is the scan, which is the prefix application. APL has no dyadic scan — x\y is expand, a function of its own — so the dyad reports that instead.
