No TODO blocks.

I must have done something wrong - it's the first time I've seen this - but then again, I don't look that closely at the output of "make test" unless
something shows as a fail. Anyway, below is the short bit of code.

Thanks
Nath

  }

  # Currently no errors

  # what about using:
  # use Test::More 'no_plan';
  use Test::More;
  $NUMTESTS = 10;
