Hey internals

Much the same as https://bugs.php.net/bug.php?id=49348 since 5.5 trying to access an uninitialized property of an object throws a notice but isn’t listed anywhere as a change that I can see.

A sample is here: http://3v4l.org/BYq1G

Should we make this apparent in the documentation?

Understood. But given for the entire 5 series it was valid I feel people finding their code randomly breaking now would expect to see it in the documentation somewhere.

Where would you suggest we place it?

Given it’s a bug fix, would it still fit here? http://www.php.net/manual/en/migration55.incompatible.php

It is still valid, and still works the same, just produces notice.
