So the code in the braces will either all complete and commit its 
effects, or else be rolled back?

Transactions sound like an extension to the language and even to 
whatever host objects the embedding provides (since they will need to 
support some kind of rollback, or at least invertible operations, or 
something akin).

This is not an operator, in any event.  It's new syntax for new 
semantics.  The first thing you could do to help is specify the 
semantics as completely as you can.
