I think the important thing is to keep in mind that the time at which
the ParenScript code gets "compiled" (however shallowly) into Lisp and
the time at which that code gets compiled into Javascript don't
necessarily have to be the same. This is what buys the name resolution
in my proposed design relatively cheaply (from the standpoint of the
cost of adding things to the ParenScript compiler).

Not necessarily. I was thinking you could have a form like
(in-parenscript-package PPP) that would set some special variable
indicating the PPP/namespace that the forthcoming ParenScript code
would use for its identifiers. At compile time, the namespace would be
populated and its binding done for name resolution, however the actual
resolution of identifiers wouldn't take place until the JavaScript
code was emitted.

I think it would have to, otherwise how would forward references be resolved?
