It’s very much needed in continuation passing / continuation pool style, so slashing it with “how many times do you need it” is an invalid argument: I’d use it all the time. It’d also help in some cases for which we have multiple proposal ideas rotating here already, which is basically multi-return (including return twice, return any number of types - not listed in advance, e.g., types created by third-party template function, etc.). I actually encountered use-cases where we had to wrap a lambda to a std::function<…>, thus have a virtual call, instead of passing a lambda to the function we’d jump to. This slows down inner loops in message processing (HFT) codes.

At any rate, it shouldn't be spelled "goto".
