1.5.0

Added

• Transducer: sexp for interpretting streams of chars or strings as separate
  SEXP strings.
• Transducer: safe for handling conditions within individual transducers.
• Reducer: quantities for counting unique occurrences of streamed items.
• Reducer: partition for splitting the stream results.
• Reducer: base-string for reducing into a simple-base-string.
• Reducer: bit-vector for reducing into a bit-vector.
• Can now transduce over a bit-vector (e.g. #*0101).
• Can now transduce specially over simple-string and simple-bit-vector,
  but only with certain compilers.

Changed

• Reducer: vector and average are now faster and use less memory.
• Reducer: string is now more efficient and yields the specialized
  (simple-array character (*)) type.
• comp is now a macro and uses less memory for long composition chains.
• All iterations are no longer implicitly wrapped in a restart-case. Doing so
  improves performance (2x in the case of SBCL, 10x in the case of ECL, etc.)
  and drastically reduces memory usage. As mentioned above, if you know that
  specific transducers may fail, you can now wrap them in safe.

Fixed

• A forgotten all? export.
