The only context I've used goto is in a TI-83 scientific calculator, but in
that, it was just about jumping around to different labels in code and had
nothing to do with functions. Though this may not have been the "canonical"
goto that Dijkstra considered harmful.

Sorry, I ran into a lot of problems trying to use the Google Groups
interface to post, so I've resorted to strictly using email. Unfortunately,
that makes the structure of the conversation less obvious to me. I'll try
to be more mindful of this in the future.
