Arghh!  It's not bad enough that "static" and "break" have two meanings each?

If, as you suggest, the addition of "register arrays" is sufficient to allow
vector optimizations, then the same suggestion with "noalias" replacing
"register" will also suffice -- and will not overload the keyword.  Whether
this countersuggestion is equivalent to the current proposed "noalias" (in the
intersection of the languages defined by both) is anybody's guess.
