loops: having my cake and eating it too?

[gusl]

One programming annoyance when writing loops is wanting to access each element of the list without passing the index, i.e. with code like: for (el in list) while simultaneously wanting to know the index without writing i=0 and i++.

I'm not aware of any solutions to this in current usage.

I would think this feature would almost be necessary in any language that pronounces "list" as "array" and pronounces "array" as "hashtable." It seems familiar from PHP:

foreach (list as $key => $value)
(do somethig)

I should also say in my shame that I second William and Chris's mapi discussion, but they got there first ;-)
