Skyscaper, good to see someone else explaining the actual interpretive methods that lawyers use.
I agree that the interpretive method is a better way to read laws (rules). Some folks feel that the only "correct" way to read a rule is literally. But in my opinion, it is just as important to look at the intent of the rules, if not more so.
D&D is unlike many games in that it actually has a Judge, the DM. The DM is empowered to make decisions. He should use the rules as a guide to those decisions, but he isn't a slave to them. He should also listen to his players point of view, as they may provide some insight.
The Arcane Initiate - Archmage is an example of where intent useful.
