There are advantages/disadvantages with everything. Can you for example show me which of those languages have a better OO system than Perl 5 with Moose? Oh my,

There are advantages/disadvantages with everything. Can you for example show me which of those languages have a better OO system than Perl 5 with Moose? Oh my, how things change... :-) I'd argue that Perl's main disadvantages are two -- the relentless trolling and that it probably has a bit harder learning curve for people to do it right. (Java isn't really in the same niche; it is more of a system language and e.g. doesn't compete in development speed with scripting languages. How is it these days -- the scripting languages on the JVM are still mostly interpreted, btw?)
