/**
 * Creates a map whose keys are tuples. Tuples are compared per-element. This
 * is useful when a key has multiple parts, but you don't want to concatenate
 * them into a single string value.
 *
 * In the Segment Cache, we use this to store cache entries by both their href
 * and their Next-URL.
 *
 * Example:
 *   map.set(['https://localhost', 'foo/bar/baz'], 'yay');
 *   map.get(['https://localhost', 'foo/bar/baz']); // returns 'yay'
