<string>Add'l note</string>
In the alpha module, i and i-setter would be aliased to X::i and X::i-setter, but print would have a method in the alpha module itself to dispatch to X::print or Y::print.

<string>usage example</string>
If you are only using namespace alpha, then you can just use class <X>, but if you use both, you'll have to prefix and say alpha::<X> or beta::<X>.
If you are only using beta::X, then you can use print() without a disambig. prefix.
