Make primitive type names reserved words (Was: Re: [PHP-DEV] [RFC] 5.4 features for vote (long))

Using them as > identifiers would return parse error for now. May have BC implications. I am not sure it is a good idea to make them reserved words without a clear reason for doing so. I'm sure some projects have defined classes with those keywords in some namespace (to ensure they wouldn't conflict with possible PHP built-in stuff) like in: namespace \Types { class Int { // ... } class Float { // ... } class String { // ... } // ... } Developer may have taken care of defining them in a specific namespace, would it be possible to not break their application while making them reserved keywords in the global namespace only? I would be +1 if this could be done for the global namespace only. However, -1 if this would break the usage of classes like \Types\Int, \Types\String, ... would break. Please, rethink your vote taking this into account. I don't think it is required to hurry up on that decision while we still don't have a *clear* proposition for scalar type hinting.
