Ah yes, I skimmed the code too quickly. Again :-P The result local holds a future/task, not the result itself, and get() may force a synchronous wait, like Task#Result in .Net. Somewhat related ramblings: I couldn't have misread the code in this way were it not for C++'s new type-inference with auto. In C#, I generally only use type-inference when first writing a statement, and then have the IDE substitute the var keyword to give a traditional 'explicit' declaration. Explicit types greatly help a codebase to be 'self-documenting'. Readability outweighs writing speed.
