Forward function declarations in a Bash or a Shell script?

https://stackoverflow.com/questions/13588457/forward-function-declarations-in-a-bash-or-a-shell-script

2nd answer looks interesting

#!/bin/bash

main() {
    foo
    bar
    baz
}

foo() {
}

bar() {
}

baz() {
}

main "$@"

Purpuse is to have interesting main logic at the top of the script and boring fat functions at the bottom.
