on bash-hackers.org I found this, which I think is the ultimate
method to write a debug-function:

_debug() {
    if $whatever_test_you_prefer; then
        _debug() {
            "$@"
        }
    else
        _debug() {
            :
        }
    fi
    _debug "$@"
}

they call it "collapsing functions":

have fun,
