I've written code that uses dirty tricks like that to avoid
duplication. It's at least as much of a problem as actual duplication
is. Generally, the 'goto' solution results in subsequent programmers
(such as my future selves) staring at the code for 30-60 seconds to
figure out what it's doing. I don't like to do that to myself, much
less to people I actually admire and respect.
