Often the lists we create have only a few elements in them. This library provides a collection type, tuple, which is optimized for these cases.
A tuple behaves exactly like a Clojure vector. However, compared lists and vectors, a two element tuple is ~2-3x faster to create, destructure, calculate a hash, check for equality, and look up in a normal Java hash-map. Some of these gains are amplified at larger sizes; a five element tuple is ~30x faster to create than a vector. Tuples larger than six elements, however, simply turn into standard vectors.
