I think it was either Bruno Haible or Sam Steingold who explained to me
once that the trick in CLISP is not to interpret, but to recompile the
function when the macro changes. This way it is more efficient than GCL
(which uses a list traversal interpreter) but behaves like an interpreter
in that sense. In any case I never studied CLISP's source code, so I cannot
be sure whether I misunderstood the email.
