oh, right, forgot about e4x.
Of course this does not say what the syntax for a meta-programmable iteration construct should be, but laziness suggests "all" is not precisely on target.
so why not make it "for each"? for-each iterates over a stream, and in the case of arrays the stream is the array values.
