Hi Dave By explicit linking are we talking about mechanism's to unambiguously reference modules that may otherwise be ambiguous? For example in java if 'Node' could refer to a Node class in several different packages, the language allows one to fully qualify the Node class eg foo.Node. Just want to make sure I'm clear on the distinction between explicit and implicit linking.
