Specials = Feature which are not part of most OO programming languages.

For really expensive algorithms it is terribly slow, sometimes you need static 
C arrays or STL...
Any experiences with Rubinius?

Why is Java inconsistent?
-no compatibility between built-in and complex types (missing operator 
overloading, complex datatype=dynamic memory...)
-inconsistent containers in stdlib (compare the operations of a built-in 
array, a List and a Map)
-Not as much OOP as in Ruby
Of course C++ is also inconsistent, it is not so OOPish, but in my opinion it 
is easier to live with C++'s inconsistence, it is sometimes ugly, but it is at 
least no problem to change container-types or to switch between built-ins and 
complex types.
