Yes, I meant for the syntax to be the shorter form, not for the
programmer to just leave off the end.

I think so too.

Also add to this, it is not always desirable to finalize an object after
use in a for loop.

I think you clarified this well.
Item 4: A list of possible syntax's with a vote at some point should do.
Item 5:
(A.) More use case's for looping blocks need to be found. I think
there may be some or many that are not obvious at the moment.
(B.) It may not cost much in performance to include the looping
behavior. Maybe this should be put off till there is a working version
of each, then comparisons of performance can be made in different
situations?
