As already argued ("fully OOP", just not in the traditional way/syntax),
not a flaw, just different ("composition-over-inheritance"). Don't you
agree with "no flaw"? You seem, by what you continued with..:

I can also see that, from the typical example. I'm however having a hard

but at least it seems it should never be worse.. Anyone have a good
example, even for a business class application..?

Yes, that is just a feeling I also have, "more concise" (compared to
single-dispatch, without considering other stuff that helps), that
automatically implies easier maintenance. Probably better "separations of
concerns". I would like to see "design by contract", should be possible
with a macro, anyone already done stuff like that?
I never looked too closely at aspect-oriented-programming (or even
subject-oriented) and AspectJ (for Java), but seems like something like
that would also be a candidate for a macro.
and it's easier to add feature to an existing code base than it is in OOP.

Do not know what you mean by "lots" left. There seem to be macro solutions
already available to even more general things than multiple-dispatch
("predicate dispatch"). Do you want some things already implemented with a
macro included in Julia's syntax without a macro needed?

For me, I'm not sure adding much more syntax is needed, maybe just add some
macros already implemented into Base? If not there, or people not aware of,
then Julia might seem less powerful.
