Open question: is the proxy mechanism still useful if a garbage
collection mechanism for collecting cycles gets into 1.6? (Neal
Schemenauer is working on something, but it's too early to tell if
it'll get into 1.6; perhaps the cost will be too high.)
If cyclic trash was collected, would you still need a proxy mechanism?
Maybe you'd use it for performance reasons, to save the GC some work,
making less trash for it to scan through, but then you're losing a
tiny bit of performance from the extra indirection on every access to
the object. My concern is simply to avoid spending time building
something that turns out to be unneeded.
