It now complies with SRFI-4 and the weird prototype based uniform array creation has been deprecated.

Generalized vectors include +strings bitvectors, ordinary vectors, and uniform numeric vectors. + +Arrays use generalized vectors their storage, so that you still have +arrays of characters, bits, etc. ** There is now support for copy-on-write substrings, mutation-sharing substrings and read-only strings.
