The dispatch library was removed from the core just before the 0.8 release.
Someone is maintaining it as a gem.
I thought the dispatch library only had the Enumerable module extensions, but I
guess it had the Job class as well since I also don't have it (using a 0.9
nightly build).
Someone who has better knowledge than me might be able to answer your questions
more thoroughly.
