After a years (or at least half a year) the CodeLocation? optimization is merged in. Added Symbol (using Racket's name for interned strings), and used it for CodeLocation? file names. The optimizes for the high number of copies - both instances with the same value and copy operations - and consistently brings down runtime by a few percent.
