It doesn't work in "classic" Bourne shell (like the one found on
Sun) but as long as the script you are working on will only be run in
bash, or on a modern Bourne shell system (like freebsd) then there is no
reason not to use it yourself.
If on the other hand the script is being used for teaching or
illustration purposes, it's better to use a syntax that's guaranteed to be
portable across platforms.
