_ is legal identifier character, so it would not be a good idea to use
it as a separator. :: on the other side is natural scope separator in
many languages. But I'm rather reluctant to start the "my separator is
better than yours" thread for the 42th time :)
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.

Not exactly. It does import, but not names just one name - the very same
name it has as an argument. The :: is used to join components of the
name. Note that you can also do:
import Foo::XML as myXML;
$a = new myXML::Data::Document();
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 :-)
