Recently I've been teaching myself lisp-- so far it seems like a very creative language, which I like, as I view creativity as one of the most important skills for a programmer to have.
There are like a million different versions of lisp it seems and no single standard implementation.
And for whatever reason I decided to write yet another...
My lisp compiles to Lua, I figured that LuaJIT2 is the fastest dynamic language VM around, so targeting it should allow my Lisp implementation to perform better than most. I had no experience with Lisp prior to this, but I certainly learned lisp fairly well while writing a compiler for it-- also improved my Lua.
It is somewhat different from the lisp norm in that it does not use lists and cons cells, instead I use a Lua table in array form. No named arguments either, although you can fake them just as you would in Lua. I also use { to introduce raw Lua code, and } to return to Lisp.
Still have to implement most of the library functions that come with most lisp implementations, and I'm sure I'll have to fix a few bugs in the compiler yet, but it is working, including support for macros.
I also saw that the creator of Lisp, John McCarthy, died a few days ago:(
