Re: [PHP4BETA] 'resource' data type

Is there documentation on this anywhere? This isn't listed among the differences between PHP3 & PHP4. There is also no documentation on the function is_resource(). This seems to be a significant change in the language (an entirely new data type), it would seem appropriate to have some documentation on this issue.
