I'm not a language implementor (maybe someday...), but following these
discussions I thought a pain point of languages like JRuby is that
many small classes need to be created, often on-the-fly, and these get
parked in the perm gen, which ends up being a constraining resource. I
thought the point of AC was to avoid current JDK classloader semantics
which prevent these "transient" helper classes from being GC'd. From
what I read on this mailing list, Charles Nutter for example was quite
excited to have them.

I may have misunderstood the point of ACs, however.
