Summary: Release note: Rewrote the joining logic to always do a full join at every join point Closes #2151 #2222 #2279 I've spent a lot of time in the last few months trying to sort out problems that arise from effects being applied too many or too few times. Fixing these feel a bit like playing wack a mole and in the end no fix goes unpunished. Stepping back a bit from the fray, it seems to me that the root cause of all this pain is the fact that joins of different kinds of completions get delayed. Before we had path conditions and the simplifier this seemed like a rather good thing since exceptional paths did not contribute values to the normal paths and we thus had fewer abstract values to deal with and fewer places where Prepack would grind to a halt. In the current state of things, however, it seems perfectly possible to join in all branches at every join point. I've had to decrease some limits, in particular the number of times we go around a loop with conditional exits. I've also had to make the test runner impose a limit on how many times the simplifier can invoke Path.implies. Nevertheless, the tests seem to pass and hopefully this will also fix quite a lot of bugs that have been unresolved for many months already.
