Thanks.  Perl 6 (and Rakudo) already allow for this -- the &hyper sub
we have now is the generic "please perform this in parallel" sub.
It's entirely valid for the compiler to recognize special cases of
parallel simple ops (like addition) and generate even better code
for those.  And the parser/language are well suited for such optimization
as well.
