The Lisp games continue. I just found out that Le-Lisp was open-sourced last year. I prefer ISLisp, but there is a nice store of ideas and maybe bits of code in there. The manual is a good place to start--I found docs for a more complete virtty library.
I have a few EISL bits-and-pieces I should finish up:
As I wrote in a previous post, for the above, I'm aiming to wrap the UNIX features (e.g. curses, setlocale, catgets, syslog) rather than implement a "Lisp" library. My current thinking is that I still want to write UNIX programs, I just don't trust C to do it any more. So ISLisp is a safer language. I'm willing to accept limitations like no nested functions in the compiled parts for this, perhaps it's better to only use the compiler for thin FFI layers anyway.

I suspect this attitude would drive some Lisp fans mad. But I'm reminded of a quote from my former supervisor, to the effect that "Lisp is nothing special". He meant it as a criticism, but I like it. I'm just looking for some standardized language with the capabilities of Algol-60, and nowadays it has to at least be memory-safe, and ideally type- and thread-safe too.
