If we go this way, it is better that the person who reimplements
Kevin's changes is someone other than you, because you looked too
close into his code and may inadvertently write identical or very
similar code.  To avoid possible legal complications, a better way is
this: you describe here, in plain English, what the changes do, and
someone else codes that in Lisp.  That way, copyright-related claims
will not hold, since the chances that the other person's
implementation will be identical are virtually non-existent, and the
ideas of the changes are not copyrightable.
