Test::HasVersion reports that the following has no version when it does:
# full code is http://sprunge.us/IIVN?pl
use MediaWiki::Bot;
BEGIN {
*PWP:: = \%MediaWiki::Bot::
}
our $VERSION = $PWP::VERSION;
This creates PWP as an alias for MediaWiki::Bot, so your version number
is whatever MediaWiki::Bot's is.
