Yeah, I absolutely didn't mean that all of these were equally essential, I was just brainstorming some of the possible permutations.

I guess the only way to avoid running out of keywords would be to have a generic clause like "on(x)", but that's probably just asking for trouble...

foreach ( $x as $y ) {
   ...
} on ( break ) {
   ...
} on ( nobreak ) {
   ...
} on ( continue ) {
   ...
} on ( nocontinue ) {
   ...
} on ( noloop ) {
   ...
} on ( loopcount == 1 ) {
   ...
}

Yeah, let's not do that! :p
