Pascal had goto. You can even do a non-local goto!
In Go you don't need goto for the sort of thing you and McVoy
talked about due to its defer statement and GC. Now granted
GC may be too big of a hammer for C/C++ but a future C/C++
add defer gainfully as the defer pattern is pretty common.
For example, mutex lock and unlock.
But I have mixed feelings about goto vs continue/break. A nested
loop with multiple continue/break can be as obscure.
