Design By Contract

folks had, or if there were plans to consider providing for this
functionality within PHP. (A longshot, I know, but it's worth a shot.)

Please refer to http://php.net/interfaces, http://php.net/spl and php-general@lists.php.net

The only language that I know of that supports Design-by-Contract
through language features is, of course, Eiffel.

PHPUnit [1] supports [2] the same approach to Design-by-Contract that
other Unit Test frameworks provide, too. But that would be a topic for
another mailinglist.
