Error handling and multi loop exiting are permitted use cases of go-to.

I also use it for avoiding recursive function calls. In theory, this will tell the compiler to just ditch the current stack and go back to the beginning of the function.

gcc can do tail-call optimization in C, and sometimes in C++. It doesn't even have to be a recursive call, tho I do think it might depends on the calling convention.
