The Gloranthan take is that the Elves - Aldryami - are more-or-less human-shaped plants, making them rather weirder in a lot of ways than their high-IQ-long-lived-humanoid equivalents.
That used to be different. There were Scheme programs running in both Scheme and Common Lisp or moving between them. For example the Yale Haskell compiler was originally developed in a Scheme dialect called T and then moved to Lisp (here Common Lisp) by embedding a shallow compatibility layer in Lisp. Another example is Common Music, a music composition system, which ran for a while both in Scheme and CL. Scheme itself was originally a hosted program on top of Maclisp. A few more Scheme implementations were written and/or embedded in Lisp - for example the Scheme variants for Naughty Dog's Crash Bandicoot and Jak and Daxter Playstation games were written in Common Lisp. The Scheme written by Peter Norvig was used in a content management system, embedded in CL.
Nowadays I don't think of Scheme as a mainline Lisp -> it moved from a close Lisp dialect to its own language with its own standards, books, user groups, libraries, implementations, applications, ...
... and then a movement was started in his name which resulted in big changes in how society worked, or at least changes in how the leaders had to act in public.
... and that movement was integrated into the establishment, first through Rome, then European and American imperialism, but the establishment continues to this day to be just as venal and corrupt as ever.
