Hey bill, that worked. I don't know why it broke the first time. I'm running Mac OSX Mavericks.
Steven: again the implementation is fine, just disorienting for a new user. If you've been developing for a while, ns::x and ns.x have pretty well accepted meanings. It's practically mandatory to read up on locales if you want to have any chance of deciphering other people's source code, but it's like chapter 26 in the guide I was reading. And the label for the concept itself is also not standard parlance. Nouns and verbs... whatever, those labels are intuitive and descriptive enough. Same with conjunctions and adverbs. And they fit the way the language was designed. But "locale"... why use that label? It's different for the sake of being different. The connotation is "the language is completely different over here", or for me it was "this is a different time zone".
