I wonder, where does Scheme fall in on this whole, uhm, scheme? Especially w.r.t. this part:

"[Clojure] doesn't have facilities to control the reader in the same way CL does: actually, in this regard Clojure is very different from Lisp — it hardly provides facilities for controlling any aspect of the language — and this control is a critical part of Lisp's DNA"

Or, is Scheme as good for stratified design as CL?
