@noescape is safer because it does not require thinking about lifetime issues for captured objects.  My hunch was that @noescape (or @autoclosure with implies @noescape) is also more common.  I had a look through the standard library and this is definitely the case there.

What does everyone think about making @noescape the default and introducing @escaping (or something similar) to annotate function arguments that do escape the call stack?
