Lisp bytecode compiler

Am I missing any special forms?
lambda if setq let quote

I know let isn't really needed because it can be implemented in terms of lambda, but recognizing ((lambda ...) ...) sounds more confusing than just using let.

I want to prove that efficient Lisp is possible regardless of the host architecture.  Doing efficient Lisp on a machine designed for it doesn't sound like something to be proud of.
