Rui CarmoThis started out as a mere stub while I put together some more resources, and over the years became a quite large list of LISP implementations I have kept an eye on.
There are matching lists for Scheme and Clojure.
Almost everybody has their own lisp implementation. Some programmers’ dogs and cats probably have their own lisp implementations as well. This is great, but too often I see people omit some of the obscure but critical features that make lisp uniquely wonderful. These include read macros like #. and backreferences, gensyms, and properly escaped symbol names. If you’re going to waste everybody’s time with yet another lisp, at least do it right damnit.

femtolispREADME)
