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

Ruby
1

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.
