| ;; the following declaration helps ACL avoid boxing.
| (declaim (ftype (function (fixnum fixnum) fixnum) lotto))

just to answer some e-mailed questions: this form shaves off 2.5% of the
execution time in ACL.  it is not strictly necessary.

|   (the fixnum	... )			; same thing for CMUCL

but in CMUCL, leaving out this result type declaration means nearly 50%
more execution time.  CMUCL lets you know that you need it, though.
