Is there interest in this? : get object from its object-specific class?

[Rick DeNatale]

The following is the culmination of a discussion on ruby-talk from a
few days ago.

Someone asked if there was a way to find the instance of a singleton
class if you only had the class. After positing a solution using
ObjectSpace.each_object, I then wrote a small extension to get it via
the hidden __attached__ instance variable.

I was then asked to submit it to ruby-core, although I'm not sure
whether it's a problem which needs to be addressed in the core.

But just in case here's the discussion. If there's interest, I could
come up with a patch for 1.8.5, 1.8.6, and maybe 1.9.

Actually, you mean Pit. He did the benchmarks. This is definitely the
way to do it right though. I would submit this to ruby-core mailing
list and see how it takes over there.
