I get 2.8x speedup in production mode over development mode.
Unfortunately, the lispworks version with no type declarations
runs 1.6x faster than that.
(The Lispworks version _with_ type declarations runs slower than
the version without. I assume it's inserting runtime type checks
to verify the decls aren't violated.)
