[RFC] Constant Scalar Expressions (re-opening)

Greetings, Unfortunately, as you will no doubt well be aware, Anthony Ferrara, aka ircmaxell, decided to cease contributing to PHP. This is not a matter I wish to discuss here, but it is relevant to the subject of this email. Because he left, he withdrew all the RFCs he authored. Since I like this RFC of his, I have decided to copy the content of it and the patch to new locations, and re-open it. The RFC, so far as I can tell, looks fairly complete as it stands. I am deciding to champion it because I think that such static expressions are useful for code readability. The intent of, for example, const TIME_PERIOD = 7 * 24 * 60 * 60; is much clearer than const TIME_PERIOD = 604800;, and there are other examples of how this could be useful. I have read through the previous mailing list discussion, and while I will admit that, yes, this RFC does not allow some possibilities that would be nice (like using constants in such expressions, for example), I think it is still quite useful and an improvement on the status quo. So far as I can tell, there are no remaining unanswered questions or unresolved issues with this, so if that is the case I would like to move this towards a vote fairly soon. The new RFC is here: https://wiki.php.net/rfc/const_scalar_expressions2 It is identical in content aside from a changed header and links. If this could be added to the list of RFCs Under Discussion that'd be great. Thank you for your time. -- Andrea Faulds http://ajf.me/
