adding to functionality of mysql_fetch_field

I'd like to see mysql_fetch_field() return as the last value in the object, the allowable values for an enum field as an array. Could I get a cc as well as a listserver group answer from the PHP guys as to whether they think this is a good idea? Is there any other EASY way to get that information about a field? It would make making <select> inputs a lot easier and more tied to the database without thinking by the programmer, and would track design changes to the database.
