Note that it=E2=80=99s a different topic though: someone going through= the Guix manual or looking at package definitions would have no reason to search for that when they see =E2=80=9C#true=E2=80=9D, for example. > In my case the first link is to the racket manual: > https://docs.racket-lang.org/reference/booleans.html > > Or this: > https://courses.cs.washington.edu/courses/cse341/02sp/scheme/basics.ht= ml > > Or the Wikipedia entry: > https://en.wikipedia.org/wiki/Scheme_%28programming_language%29 > > Any kind of search quickly reveals that booleans in Scheme are coded > using #t and #f; whereas to find #true and #false, my impression is that > one already needs to know that these are possibilities.
