`#pretty_print` also now just uses Set instead of self.class.name.

It is intended behavior.  Core classes generally do not have different output in subclasses (e.g. Hash, Array, String).

Now that `Set` is a core class, I think it's worth considering for `Set#inspect` to return a string like: `Set[1, 2, 3]`

Hash, Array, and String don't say the name of the class in their inspect, though.

I'm certainly in favor of `Set[1, 2, 3]` (this is an improvement I make wherever I subclass Set already), but this seems orthogonal to identifying the class of the inspected object. I don't know any classes that show a base class name instead of self.class name.

Not terribly important to me since I override inspect anyway, fine by me to close if 'Set' is preferred over class name, but class name seems more correct in my opinion.

Agreed, if the `inspect` shows the class name, it should show `obj.class.name`, not some superclass which would be very confusing.
Otherwise all objects with default inspect would be `#<Object: ..>` and that would be no good.
