a) I was talking about namespace name "A_B" not class/function name.
_ 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 :)
b) So as far as I understand "import" doesn't actually *import* names
from specified
namespace to the current one but just renames long namespace name to a
shorter one. And if I get it right the separator in the namespace name
is allowed
and required only to express default name when importing without "as".
Am I right?
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();
if you wish so.
