It now complies with SRFI-4 and the weird prototype based uniform
array creation has been deprecated. See the manual for more details.
A non-compatible change is that characters can no longer be stored
into byte arrays.
Some non-compatible changes have been made:
- characters can no longer be stored into byte arrays.
- strings and bit vectors are no longer considered to be uniform vectors.
There is the new notion of 'generalized vectors' and corresponding
procedures like 'generalized-vector-ref'. 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.
