Indeed. That is almost the only place I use 'goto' in C, and the
almost the only place I see others use it. Very occasionally, you see
a the error handling goto refactored into a backwards "goto retry":
I happen to find the latter easier to read.
Fortunately, Python doesn't need goto to deal with things like that.

I've tried to use setjmp/longjmp for error handling a few times. It
never went well...
