I'm curious: What's better about Swift's `defer` than `try/finally` in ObjC or Java (or virtually any other language since 1990)?

.@iTod defer doesn't have to be used with try-catch; put your cleanup code right by the initialization. e.g. file open/close.

@owensd I'm pretty sure you misunderstood me. I said `try/finally`, not `try/catch` nor `try/catch/finally`.

.@iTod that's what's better: there is only one cleanup mechanism. Promotion to a throwing function doesn't require moving code around.

@owensd And as far as 'one cleanup mechanism' I'd say `try/finally` is even less conceptual overhead than `defer`, not to mention familiar.

@iTod also, finally happens in order, defer happens on scope exit.

@owensd I don't grok the difference there. Seems like both offer fine-grained ordering control. Maybe `finally` even finer control?
