Rangeable is a language-neutral, generic, integer-coordinate closed-interval set container. It pairs hashable elements with their merged disjoint integer ranges and answers three queries: by-element ranges, by-position active set, and by-range transition events. The Ruby reference implementation follows the Rangeable RFC normatively, including idempotent containment fast-path, lazy boundary-event indexing, and first-insert deterministic ordering.

It accepts ranges or items with ranges and compacts them.
