  • Lunar Programming Language by David A. Moon
    Lunar is my attempt to distill 40 years of programming language experience into the "best" language I can come up with. I hope that this will bring some forgotten ideas back into the spotlight of public attention.

  • Lisp vs Forth
    Henry Baker wrote a beautiful little paper (see
    https://www.plover.com/~mjd/misc/hbaker-archive/ForthStack.html) showing
    the mapping between Linear Lisp (a Lisp in which all variables are
    referenced once and only once) and a Forth-style "frameless stack".  There
    is also a discussion of Forth as a set of linear combinators: Manfred von
    Thun's Joy https://en.wikipedia.org/wiki/Joy_(programming_language) is a
    Forth-like using nested lists in which the stack is the top-level list.
