- sequence(:Start, :Element, :Sep, :End, ?List)// is semidet
- Match or generate a sequence of Element enclosed by Start end End,
where each pair of elements is separated by Sep. More formally, it
matches the following sequence:
Start, Element?, (Sep,Element)*, End
The example below matches a Prolog list of integers:
?- phrase(sequence(("[",blanks), number, (",",blanks), (blanks,"]"), L), `[1, 2, 3 ] a`, Tail). L = [1, 2, 3], Tail = [32, 97].
