The implementation for CMUCL was largely done by Pierre Mai, with help
from members of the @code{cmucl-help} mailing list. Since CMUCL and
SBCL are similar in many respects, it was not too difficult to extend
the low-level implementation optimizations for CMUCL to SBCL.
Following this, SBCL's compiler was extended to implement efficient
compilation of modular arithmetic (@pxref{Modular arithmetic}), which
enabled the implementation to be expressed in portable arithmetical
terms, apart from the use of @code{rotate-byte} for bitwise rotation.
