Me neither :-) :: is perfectly good for me. I just missed the point of
having it more
then once if it's only purpose is to separate default short name part
from whole
name.

Now that explains a lot :-) If I get it right I can have namespaces
A::B::C and A::B::D
then create an alias for A::B with "import A::B" and use B::C::foo()
and B::D::foo() in
that file. Thats nice. Looks like namespace nesting though it isn't :-)
