Functons

all

pred:all(c, pred)

Evaluates c as a list of elements, then for each element evaluates pred as a boolean. Returns true if all evaluate as true.

any

pred:any(c, pred)

Evaluates c as a list of elements, then for each element evaluates pred as a boolean. Returns true if at least one evaluates as true.

enum-while

pred:enum-while:varName(start, end, expr, condition)

Evaluates start and end as integers, then assigns to varName each value between start (inclusive) and end (exclusive) and evaluates expr as a list of elements. Before evaluating expr, evaluates condition as a boolean. If condition is false, then stops iterating the list. Returns all elements in a single list.
