=item B<summary>

    my @tests = $Test->summary;

A simple summary of the tests so far.  True for pass, false for fail.
This is a logical pass/fail, so todos are passes.

Of course, test #1 is $tests[0], etc...

=cut

sub summary {
    my($self) = shift;

    return @Test_Results;
}

=item B<details>  I<UNIMPLEMENTED>

    my @tests = $Test->details;

Like summary(), but with a lot more detail.

    $tests[$test_num - 1] = 
            { ok         => is the test considered ok?
              actual_ok  => did it literally say 'ok'?
              name       => name of the test (if any)
              type       => 'skip' or 'todo' (if any)
              reason     => reason for the above (if any)
            };

=item B<todo>

    my $todo_reason = $Test->todo;
    my $todo_reason = $Test->todo($pack);

todo() looks for a $TODO variable in your tests.  If set, all tests
will be considered 'todo' (see Test::More and Test::Harness for
details).  Returns the reason (ie. the value of $TODO) if running as
todo tests, false otherwise.

todo() is pretty part about finding the right package to look for
$TODO in.  It uses the exported_to() package to find it.  If that's
not set, it's pretty good at guessing the right package to look at.

Sometimes there is some confusion about where todo() should be looking
for the $TODO variable.  If you want to be sure, tell it explicitly
what $pack to use.

=cut

sub todo {
    my($self, $pack) = @_;

    $pack = $pack || $self->exported_to || $self->caller(1);

    no strict 'refs';
    return defined ${$pack.'::TODO'} ? ${$pack.'::TODO'}
                                     : 0;
}

=item B<caller>

    my $package = $Test->caller;
    my($pack, $file, $line) = $Test->caller;
    my($pack, $file, $line) = $Test->caller($height);

Like the normal caller(), except it reports according to your level().

=cut

sub caller {
    my($self, $height) = @_;
    $height ||= 0;

    my @caller = CORE::caller($self->level + $height + 1);
    return wantarray ? @caller : $caller[0];

=item B<_sanity_check>

  _sanity_check();

Runs a bunch of end of test sanity checks to make sure reality came
through ok.  If anything is wrong it will die with a fairly friendly
error message.

=cut

#'#
sub _sanity_check {
    _whoa($Curr_Test < 0,  'Says here you ran a negative number of tests!');
    _whoa(!$Have_Plan and $Curr_Test, 
          'Somehow your tests ran without a plan!');
    _whoa($Curr_Test != @Test_Results,
          'Somehow you got a different number of results than tests ran!');
}

=item B<_whoa>

  _whoa($check, $description);

A sanity check, similar to assert().  If the $check is true, something
has gone horribly wrong.  It will die with the given $description and
a note to contact the author.

=cut

sub _whoa {
    my($check, $desc) = @_;
    if( $check ) {
        die <<WHOA;
WHOA!  $desc
This should never happen!  Please contact the author immediately!
WHOA
    }
}

=item B<_my_exit>

  _my_exit($exit_num);

Perl seems to have some trouble with exiting inside an END block.  5.005_03
and 5.6.1 both seem to do odd things.  Instead, this function edits $?
directly.  It should ONLY be called from inside an END block.  It
doesn't actually exit, that's your job.

    $? = $_[0];

    return 1;
