Foreach Closures?

[Kevin Cox]

I was wondering about the foreach statement and when you implement
opApply() for a class it is implemented using closures.  I was wondering if
this is just how it is expressed or if it is actually syntatic sugar.  The
reason I aski is because if you have a return statement inside a foreach it
returns from the outside function not the "closure".

I was just wondering if anyone could spill the implementation details.

Thanks,
Kevin
