[Perlunit-users] Proposed behavioural change for assertions with undef

[Adam S. <ad...@sp...>]

I'm about to change things so that these will no longer pass:

  $test->assert_str_equals(undef, '');
  $test->assert_str_equals('', undef);
  $test->assert_num_equals(undef, 0);
  $test->assert_num_equals(0, undef);

since it's very easily conceivable that they could result in passes
where there should be failures, and that is a huge no-no for test
frameworks.  If someone really wants to consider undef as equivalent
to '' or 0, they can always manipulate the values before passing them
as parameters.

Speak up very swiftly if you have any objections ;-)
