Is (TRUE exp) a legitimate alternative to (BLOCK exp T)?
Or is it intended that a compiler might optimize away the
evaluation of the exp.
It seems to me that the definition of "optimization" precludes
anything which changes the semantics of an expression. ie,
optimizations (in any language) only make sense when the compiler
can prove that you'll never know the difference. If they're not
defined that way, they're not "optimizations", they're just "hacks".
