WebLisp: A Lisp Interpreter that runs inside the browser

And a quick shout-out to JSLisp : <a href="http://joeganley.com/code/jslisp.html" rel="nofollow">http://joeganley.com/code/jslisp.html</a> . That was an educational piece of JS for me.

Arclite is a subset of Arc written in Javascript.<p><a href="http://jonathan.tang.name/files/arclite/index.html" rel="nofollow">http://jonathan.tang.name/files/arclite/index.html</a>

Sweet. It appears to have proper tail recursion.<p>(define (fib n) (fib-help n (lambda (fn fn-1) fn)))<p>(define (fib-help n k) (if (&#60;= n 1) (k 1 1) (fib-help (- n 1) (lambda (fn-1 fn-2) (k (+ fn-1 fn-2) fn-1)))))<p>(fib 1000)

So, are there any in-browser lisps that, you know, do something? Maybe one that plays in the Pipes space, letting you work with feeds of various sorts?

How many of these are there anyway?

No macros?
