While it's true that comparing learning a new computer language and learning a new spoken language isn't always the proverbial apples-to-apples proposition, there are a few crucial similarities. The first, of course, is the un-learning that must happen (particularly if the new language is only your second.) I didn't stumble upon another similarity until just today, however: Namely, how having to think about the conventions of a new language forces you to better understand the one(s) you already consider "native."
Given that I will never touch Objective-C again--at least not without considerable financial incentives--at least I've salvaged that scrap of enlightenment from the past three days. Silver linings and all that... And, in the spirit of Views, consider it paid forward.
