I would never allow myself to even think that. Maybe you're right and it is
just obvious to me as i wrote the patch.

Na 'readable' means readable whatever i said elsewhere, no? Not logical?

Erm i heared somebody asking for 'friend' during php 5.0 development; And it
wasn't me, i swear.

ouch!
Well, it's just a stupid patch that comes without a new keyword. Mayke it
'private readable'.
Btw, you asked for for a new visibility keyword starting with P: Promulgate,
Popularize, Proclaim, Pliable. Those are at least remotely related to what
they should express. Actually promulgate is in my humble opinion quite
close :-)
And since you get what you deserver you'll find the updated patch attached.
Before you ask making it a single keyword on its own and giving the member
private or protected write visibility is of cause very easy, too.

Best regards,

before anyone gets that wrong again, i am having fun with the patch.
