Like, this is verbose AF. null|bool|int|float|string|array|object|resource For the long term good of the language I'd prefer type aliases (or typedefs or usings or whatever you want to call them. use mixed = null|bool|int|float|string|array|object|resource; use scalar = null|bool|int|float|string; use number = int|float; That said, baking 'mixed' in as an implicit alias of the above isn't problematic for that future. -Sara
