Using labels (ex. break "xyz"), why add another keyword ("break") when "exit",
which IMHO has the same meaning, could be used instead?

Without using labels, ok, "break" could be used to distinguish an exit from a
if-then-else construct from an exit from a loop, but is this a sufficient reason
to add it?
