I've been experimenting with the new PO/MO file readers that @stealth35 added recently. There is one very unfortunate thing missing from this however, is that they don't parse the plurization rules. In Gettext, these are part of the header so the framework doesn't need to know hard coded values as is required in Symfony2. In order for these readers to be useful, they really need to parse this information. It will require an extra property in the MessageCatalog class I guess.
