/**
 * Returns a new lazy [Iterable] with all elements that satisfy the
 * predicate [test].
 *
 * The matching elements have the same order in the returned iterable
 * as they have in [iterator].
 *
 * This method returns a view of the mapped elements. As long as the
 * returned [Iterable] is not iterated over, the supplied function [test] will
 * not be invoked. Iterating will not cache results, and thus iterating
 * multiple times over the returned [Iterable] will invoke the supplied
 * function [test] multiple times on the same element.
