I think we're generally very comfortable with this rule; forgetting to handle a return value (maybe because you expect the function to be mutating) is a pretty common mistake, and "_ = " seems nicer than the old C equivalent "(void)". Do you find yourself writing a lot of functions that return non-void results that you frequently want to ignore? Maybe there's some idiom we could do a better job of recognizing. John.
