The scanner compiler uses visit c w f v to compose a scanner that visits with f every element in a sequence of kind c in the context w. The first element is visited with the initializer v, and each following element is visited with the value returned by the preceding scanner.

The scanner compiler uses finish w to compose a scanner that recognizes the end of the sequence that started upon producing w.

The scanner compiler uses pair c k v to compose a scanner that recognizes a pair of kind c comprising a first item recognized by k and a second item recognized by v.
