Unfortunately AFAIU the "Modified code" license addition (where does it
comes from?) still does not qualify the license as free.

"On Lisp" official page is here:
http://www.paulgraham.com/onlisptext.html, book and code (mechanically
extracted from the TeX source files of _On Lisp_) is copyright by Paul
Graham.  AFAIU today both the code and the book are freeware but not
free.

The original code (officially linked in the book web page) is here:
https://sep.yimg.com/ty/cdn/paulgraham/onlisp.lisp?t=1595850613&

A good chance to ask Paul Graham (and Dalek Baldwin... or Kyle Littler?)
to release the code as free software?  :-D

Thanks! Giovanni.

P.S.: I'm not familiar with Common Lisp but is it possible that the
functions from "On Lisp" has been somehow replaced or incorporated in a
proper library? ...I'm going to ask on guix-devel.

This alone will not fix the problem with "point 3." of the Weir license,
but would be a start.
