"Premature optimization is the root of all evil."
-Don Knuth
Don't use goto's for the sake of efficiency until you know (from
profiling) that it's worth it. Really, code becomes much harder to
maintain when it's not well written.
If you've never done it, emerse yourself in a language like lisp or
scheme that has no concept of goto, not even in its socially
acceptable forms ("contine," "next," etc.). You'll discover after a
few weeks that goto is never necessary. That insight will help your
write better code.
If you need a goto, use it. I've been programming for over a decade
and I've never needed a goto.
