I may have asked the wrong question. It's hard to evaluate the many OOPs out there. Maybe what I'm looking for is a sample problem that is solved in several dialects of OOP. That would provide some metrics.

Having spent the day in C#, the object.method syntax is starting to grow on me. But that's just encapsulation. A Forth could take a foo.bar syntax to mean "look for bar only in the foo wordlists". After all, Foo can have more than one wordlist depending on its ancestry. AFAIK some of the OOPs support FOO.BAR as FOO BAR to avoid patching the interpreter.

The base class could have some toolkit words: foo.words lists the words in the foo wordlist(s), foo.help lists a glossary, or foo.edit opens the source in an editor.

Maybe I'm oversimpifying. Many OOP features are less important to supply in Forth because load order and CREATE DOES> provide much of their functionality already. 

The primary use of OOP seems to be encapsulation, followed by its cousin polymorphism. Rather than adopt an OOP with hundreds of LOC, I might adopt one with tens of lines.

But that takes me back to Stephen's point that nobody can write OOP-based libraries because of the Babel of OOPs. I'm looking for one to emerge from the primordial soup. Something that doesn't eat up a lot of RAM in an embedded system, for starters.
