Subject: Re: [PHP-DEV] New "static" keyword doesn't have private access?

Hello,

First, to be clear, you're mixing two kinds of static keywords:
1) a static method/property which represents a method/property that is bound
to a class only
2) the "static" class reference

Of course, private properties (static or not) are not accessible from any
other scope than the one in which they are defined. In this context,
static::$cls is translated to B::$cls, and will issue an error as B::$cls is
not accessible from A's scope.

Regards
