Micheal Kimsal has pointed out another "bugbear" he's found in his work with PHP - this time it's with the use of class constants.

My issue is not with the language itself (this time!) but how this sort of documentation is handled. Updating public documentation well ahead of a release creates confusion.

He's referring to the documentation for the class constants not quite matching up with the current functionality (resulting in a T_PAAMAYIM_NEKUDOTAYIM). He wants consistency in the documentation and maybe references to what it requires to use a certain bit of code.
