Yes but mixing declarations and conditionals is a bit like demanding
the waiter bring you your main course and pudding in the same plate
and then complaining when it tastes funny. There is a certain cost to
providing a rich language like Perl in terms of complexity and
sometimes you have to accept that you have to read the documentation.
