There's quite a bit of code out there which uses it to jump to a common set of 
error handling code, which can actually make functions cleaner in some cases. 
Phobos even does this a few places (though not many).

Also, as I understand it, there are cases in low level code (where you need 
every cycle that you can get) that using a goto to get out of a section of 
code can be more efficient than getting out of it in the ways that you would 
more typically do. I haven't personally run into that sort of thing though, 
since I don't generally write code that low level.

And just because you or I don't use it much, doesn't mean that people 
programming in other domains don't need it for use cases that we never run 
into. goto is just one of those things that a systems language is bound to 
have.
