Re: Why isn't base class constructors or destructors required to be called?

Hi Johannes. > you should look harder: > http://www.php.net/~derick/meeting-notes.html#function-require-construct-to-force-calling-the-parent-s-constructor Thanks for your reply, but I've actually seen that one. However, no _reason_ for not allowing/requiring this in "userland" is given. Only the conclusions: "Conclusions: - We add a flag to the class structure to record this - We do not add new syntax for this to userland" Reading this again, I'm wondering if I interpret it right in that there will be no way to enforce this in PHP code? If so, why not?
