I think this reason is misguided. Most expressions do not depend on
their
order of evaluation, so even if the language specified the order the
compiler
could still rearrange things as it wished. It is for those few others
where
consistency rather than efficiency is most important, else programs
stand
the risk of working "accidentally" and then failing mysteriously due
to a
change in environment.
