What's that "for i, val : list: ..." syntax? -

i remember that syntax existed in language! for i, val : list {...} {int = 0; val : list {...; i++;}}, language that?

this exact syntax unknown (and won't work in language). can offer be

java iterators:

for(string : new string[]{"one", "two"}) print(i);

c foreach macro

for_each_item(i, processes) { i->wakeup(); }

javascript foreach:

for each (var property in obj) { print(property); }

syntax
