Can you give a specific example or two to chew on? Preferably something whose lifetime would optimally be shorter than the containing window's? Jim Blandy has been giving ideas for certain classes of problems, but I can't tell how many realistic situations those ideas might address. Sure, weak refs could solve them all these problems in one fell swoop, but weak refs (or other observable GC) would also paint us into a corner and prevent many tuning optimizations. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
