construct: % -> Stream S

construct(t) converts an infinite tuple to a stream.

filterUntil: (S -> Boolean, %) -> %

filterUntil(p, t) returns [x for x in t while not p(x)].

filterWhile: (S -> Boolean, %) -> %

filterWhile(p, t) returns [x for x in t while p(x)].

map: (S -> S, %) -> %

map(f, t) replaces the tuple t by [f(x) for x in t].

select: (S -> Boolean, %) -> %

select(p, t) returns [x for x in t | p(x)].

stream: (S -> S, S) -> %

stream(f, s) returns [s, f(s), f(f(s)), ...].
