Yup. Even Java has Class as object. If D copied most of OOP from Java it

kind of saying "you have RTTI but it's crippled just in case if it is of

I would not compare Java's Class with classes in Objective-C and Ruby.
In Objective-C and Ruby classes are objects with their own hierarchy of
inheritance. Example in Ruby:
class Foo
def bar
@instance_variable = 1
@@class_variable = 2
end
# class method
def self.bar
@instance_variable_on_the_class = 1
@@class_variable = 3
end
end
a = Foo
instance_of_foo = a.new
Yes, it's OOP classics I think. Dynamic languages are easier in this
regard. But let's not detract from original topic - locking.
