I do it all the time in one of my languages. But you need to know what is 
happening.

In my case, I use it for threaded code, where you do a goto, not a call, to 
the start of one function, and that then terminates by doing a goto, not a 
return or call, to the next function.

There are a few other uses, but it's usually too risky to do with a 
language/compiler you're not familiar with, even if there is some way of 
doing it.
