I've found that people who engage in handwringing about efficiency of a
system they don't understand produce terrible code. Try implementing it
before worrying about micro-optimizations.

You're over-thinking the semantics too. The whole point of Stefan's
proposal is that it's very simple, but still delivers most of the
benefits of unrestricted reader macro support. Qualifiers like "by
convention, identifiers would have to restricted..." is a step down the
road to adding overgrown Clojure ceremony for everything, something I
definitely do not want in Emacs Lisp.
