Is there any progress on this?  I notice it is not yet in the core.  I'm in need of an AMSL split-like environment but the above doesn't work entirely as expected.  Below is an example.

Any ideas?
Thanks, Dave

It will be a while before I am able to get all the bells and whistles
(take care of where the formula number is to be placed, and how how the
formula is to be aligned).
