-=head2 Diagnostics
-
-If you pick the right test function, you'll usually get a good idea of
-what went wrong when it failed. But sometimes it doesn't work out
-that way. So here we have ways for you to write your own diagnostic
-messages which are safer than just C<print STDERR>.
-
-=over 4
-
-=item B<diag>
-
- diag(@diagnostic_message);
-
-Prints a diagnostic message which is guaranteed not to interfere with
-test output. Like C<print> @diagnostic_message is simply concatinated
-together.
-
-Handy for this sort of thing:
-
- ok( grep(/foo/, @users), "There's a foo user" ) or
- diag("Since there's no foo, check that /etc/bar is set up right");
-
-which would produce:
-
- not ok 42 - There's a foo user
- # Failed test (foo.t at line 52)
- # Since there's no foo, check that /etc/bar is set up right.
-
-You might remember C<ok() or diag()> with the mnemonic C<open() or
-die()>.
-
-All diag()s can be made silent by passing the "no_diag" option to
-Test::More. C<use Test::More tests => 1, 'no_diag'>. This is useful
-if you have diagnostics for personal testing but then wish to make
-them silent for release without commenting out each individual
-statement.
-
-B<NOTE> The exact formatting of the diagnostic output is still
-changing, but it is guaranteed that whatever you throw at it it won't
-interfere with the test.

+B<NOTE> By historical accident, this is not a true set comparison.
While the order of elements does not matter, duplicate elements do.

+ eq_set([\1, \2], [\2, \1]);

Returns the Test::Builder object underlying Test::More for you to play
with.

So the exit codes are...
0 all tests successful
- 255 test died
+ 255 test died or all passed but wrong # of tests run
any other number how many failed (including missing or extras)
If you fail more than 254 tests, it will be reported as 254.
+B<NOTE> This behavior may go away in future versions.

=item Overloaded objects
-String overloaded objects are compared B<as strings>. This prevents
-Test::More from piercing an object's interface allowing better blackbox
-testing. So if a function starts returning overloaded objects instead of
-bare strings your tests won't notice the difference. This is good.
+String overloaded objects are compared B<as strings> (or in cmp_ok()'s

However, it does mean that functions like is_deeply() cannot be used to
test the internals of string overloaded objects. In this case I would
