I think this whole thread is at least a year early, if not two. With all due respect to the OP, calling for a merge of PHP and HHVM at this time shows a lack of understanding about the full breadth and reach of PHP, and the fact that HHVM is a complete reimplementation of the language and runtime. -Sara P.S. - FWIW, the fix for that bug (hate to play semantics, but it's a bug, not a parity gap) is on its way out. Basically just been delayed by the holidays.
