Since interpreter/compiler/strange evaluator consistency is one of the
few things that almost everybody agrees is good about Common Lisp,
it should take precedence over anything that would damage this;
COMPILER-LET should be flushed, and EVAL-WHEN, and I wouldn't mind
some constraints on macros in general, although there's not much
prospect for that...

For PCLS we took advantage of subsetness and totally ignored COMPILER-LET,
since nobody could figure out what it was really for or how a user could
use it in correct code.
