Re: enhanced foreach loops

I have to agree with Ken, its a interesting idea and also a very useful one
since it will allow to remove some redundant cycles/assigns to obtain that
value.

On the issue of the value, I guess the logical one would be NULL (since its
not assigned/existent) or optional, which I don't like but possible, to
break cycle if one of elements don't exist.
