Yes, in this case they're mine. However, in the general case, I want to:

• use a module (which possibly has a Deeply::Nested::Package::Name),
• not have any names dumped into my script's namespace (except the package I just used), and
• be able to use the functions/variables in the module without having to type the Deeply::Nested::Package::Name every time.

Personally, I tend to prefer fully-qualifying names, otherwise I get confused where the name comes from.

Comment on Re^2: How can I use a module via a short name or alias?
