And I did: 

module A
  def A.a
  end
end

and was surprised to discover that I could call a as either A::a OR
A.a

Is this intentional?

On another note, the way the Pick Axe book describes Modules, it would
seem that only methods and constants can be placed in a Module. In
fact, it seems to be possible to put classes and plain old executable
code in modules as well, and I find myself quite confused as to the
rules. I'd like modules (when not used for mixins) to look just
exactly like simple namespaces, but I'm not sure they are exactly the
same as what I think that means... (in particular, having to precede a
module method's name by the module name, seems to make things not
quite transparent). Is it just me that's confused, or would it be
better/clearer if a module and a mixin were really two separate
concepts, perhaps with two separate names?
