Neat. So what's the type of nil? :) It's obviously not a list. How do
you declare it? And why is it better than completely generic types (if
you still have to check whether it's a list or nil in every list
operation, you could just as well check for all other types)?

Actually I'm really interested about your method of client-dependant
hypertext formatting. Start a new thread? :)

Of course not. I'm saying what /needs/ to be stored (i.e. semantics).
Syntax should me more convenient than this.

I agree here. Lightweight objects are Good Thing.

Err, no, if you said it was safe, I believe you. This is independant
statement: I don't like thinking about implementation when designing
the language. It can destroy the design (the problem is called
'premature optimization'). I'm not saying it did, in your case...
How about starting serious thread on language design, with concrete
language proposals?

Jon asked not to. :)
