This touches on another important question -- how do we plan to represent: 1) An operator which is only applicable when an operator is used on two dissimilar types (e.g. TimeTuple x float)? 2) An operator which can be applied to an object, but with a primitive or otherwise non-extensible type on the left hand side of the operator (e.g. float x TimeTuple)? 3) An operator which can be used with multiple types, but whose meaning and/or return value can change based on what types are used (e.g. Matrix x Matrix vs. float x Matrix)? -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: https://www.php.net/unsub.php
