I use it all of the time. But then I remove it. 

It's the same with continue, except that I imagine the reason to be different. I took a decade's break from programming and started up with Lua. Not having `continue`, I'm guessing that I didn't organize loops in that way. Every so often, I think I need it, but eventually, as then solution developes I end up removing it. 

I suspect that with goto, it's slightly different, in that I suspect that I was never smart enough to use it well. When I try to use it, it's in some kind of progressive state machine, but eventually, the more familiar patterns prevail and I can't justify my own fanciness.
