I'll add that switch has accommodated all of our upgrades surprisingly well, to the point that I am very hopeful we don't have to pay the very costs of a totally new construct. The major cost, IMO, would be confusing the language by providing two complex but incompatible constructs with strongly overlapping functionality. I'd very much rather add new constructs because the language can't really express something type-safely, or because there is a 30x gain in compactness for some common construct. Then the overlap issue doesn't appear. — John
