well as get_change_times method from Wala.pm.

Got rid of label display where links aren't displayed.

print a(
    {
      title => 'previous month',
      href  => '/2008/2'
    },
    'go to the previous month'
  );

Which should give

  <a title="previous month" href="/2008/2">go to the previous month</a>

Or something very similar.  I suppose there are no guarantees about the
order of attributes.

stuff and use it as a testbed going forward.
