Introduce RefCountedException?
Also that the pattern almost always is "throw new" and *very*
rarely it is "Exception e = new ...; throw e;". I think we might
be able to take advantage of that (e.g. "throw new E" could be a
special case of "new" that allocates on some sort of "Exception"
heap that is manually managed, or recognize RefCountedException).
