It has been clarified, that the entire Wisp language specification is
Expat-licensed.  As such, we can apply the Expat license to this
project as a whole, but we still need to be careful when distributing
Guix packs.  (We can, however, form small bundles consisting of
Tsukundere + Wisp + this repo when considering only the /share/guile
and /lib/guile portions of Wisp.)
