I’ve made the rethrow in WithStatement now throw through our helper and updated the interpreter to do nothing special w/ repros making it closer to the compiled code path.

Nice checkin Message! Not to mention impressive, lots of good stuff there.

20634, 15428, 20051, 4565, 21929, 17235, 20039, 19278, 19005 (and 
possibly others) all look like good candidates for backporting to 2.02.

Any idea when 2.0.2 might be done?
