This seems more like bad compiler design than anything. From the users perspective a for loop is a read-only operation and shouldn't be copying anything. I know it's how the enumerator thing is done but that may have been a bad design from the start or needs some extra optimization somewhere.

For OP I would just kill the for-in loop in favor of a normal for-do loop and be done with the problem.
