I'm merely pointing out the burden of adding new language features. This is not to deter from adding them, but to caution against excess. There is a cost to learning a new language feature, updating its documentation, considering its trade offs in software design, etc... Part of this cost is shared between those who maintain PHP and those who use PHP. My statements here are intended to be cautionary, not dissuasive.
