Bug description: namespace visibility
Description:
------------
When PHP first introduced visibility, it did not yet have namespaces, so
the only applicable visibility schemes were related to classes -- members
were either global (public), or local to the class (private), possibly
including parents and children (protected).
But with the addition of namespaces, there is now a need for a visibility
scope between public and protected. Developers (like me) will use
namespaces to create packages -- collections of classes that are meant to
work closely with each other. In this context, it would be very convenient
to be able to make members visible to other (unrelated-by-inheritance)
classes within the same package (namespace), but hidden from the world
outside the package.
Since the 'namespace' keyword is currently only allowed on the first line
of a file, and therefore could not occur inside a class, I suggest re-using
it for this purpose rather than introducing another reserved word.
Reproduce code:
---------------
<?php
namespace Test;
class A {
namespace static $nsVar = 'Test::A::nsVar';
static function test() {
echo __CLASS__." can see ".A::$nsVar."\n";
}
}
class B {
static function test() {
echo __CLASS__." can see ".A::$nsVar."\n";
}
}
Test::A::test();
Test::B::test();
Expected result:
----------------
Test::A can see Test::A::nsVar
Test::B can see Test::A::nsVar
Actual result:
--------------
(syntax error on 'namespace', line 4)
