This only works if the repeated part happens to be at the
tail of each case.
IME that seems to be the most common situation.
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.
The problem is having to stare at the code for even longer to figure out
the even dirtier tricks you had to use to avoid gotos.
