Std.Iter.Mapped

type

This declaration introduces a public type.

What it does

A sequence whose items are another's, transformed.

Nothing is computed until the walk asks for it: advance transforms one

item and returns. Building a Mapped over a sequence of a million does no

work at all, which is what "lazy" has to mean to be worth having.
