> among the Lisps, though tellingly not the case with Scheme, the association list was already in place An association list is just a list which elements are conses. I'm fairly certain that cons, car and cdr were part of Scheme since the beginning and they are all you need to build assoc and friends. Scheme lacked a proper hashtable datatype though, which was present in some other Lisps.

he was talking about scope here. hashes do not help much. assoc lists were important to implement dynamic environments simple and fast, which is not so easy with hash tables. In assoc lists you tolerate duplicates, but by putting new at the beginning you override/"shadow" the old ones, until you leave scope and use the old assoc list. and share the data! with hashes you have to actively delete or copy the tables. non…

Googling turned up several on just the first page of results: http://www.biwascheme.org/ http://sisc-scheme.org/sisc-online.php http://lisperator.net/slip/ http://alex.nisnevich.com/ecmachine/ But the parent is really the right answer -- ClojureScript is actually targeted at meeting modern web development challenges and has a thriving ecosystem of powerful tools for the same.

Compiling to Javascript isn't what I find interesting. I'd like support for . Pure Lisp, compiled for the user's browser and OS. No Javascript anywhere.

You can do this now (console-log "Hello, world!")

Scheme has plenty of dirty imperative methods, if you want. Their names end with `!`, like `set!` to mutate a variable. In most cases it's cleaner to be purely functional, but it's not required. Predicates end with `?`, like `equal?`. This naming and consistency makes it easier to learn Scheme. What makes Common Lisp more practical is libraries. Hairy and crufty some may be, but many of them, and many of good quality…

I really don't like the Common Lisp naming and the 2-space nature of the language makes this even worse. The conflict of the implementors appears in many places. I like many things about scheme, but I won't whitewash it's problems. Non-standard, non-portable racket libraries aren't the answer to scheme's basic nature (though I believe r7rs-large will solve a lot of these issues). More serious dealbreakers in my work…

This I would love to see. I'm not aware of any project working to enable Scheme or Common Lisp in the browser, though. Anyone else?

ClojureScript is a subset of Clojure that compiles to Google Closure-optimized JavaScript, so close enough, right?
