Henning Schmiedehausen commented on VELOCITY-443:
-------------------------------------------------

That implies that iterator() always returns an Iterator object which might lead to hard-to-find ClassCastExceptions. I'd appreciate a catch (ClassCastException ) with a meaningful error message. Apart from that: Nice.

> In the new for loop in Java 5 e.g.
> for(Object obj: iterable)
> the collection iterated only needs to be of type Iterable
> However, In Velocity a foreach loop must be either a Collection or a Map but cannot be just an Iterable.
> Suggestion, support Iterable containers.
