Yeah, dynamic scoping is cool. ;)
I would also be interested in that. The Scheme dictum seems to be that
you can implement dynamic scoping yourself, as some kind of special case
of lexical scoping (which is true but besides the point IMHO). Since Arc
seems to be closer to Scheme than to Lisp, I wonder what the idea here is.

You can, but the serious Scheme implementations usually have
"native" implementations of srfi-39 (parameters).
