Subject: forbid use declaration outside of a namespace in PHP 7
From: php@tutteli.ch ("Robert Stoll")

Heya, 

I always found it very ugly that it is possible to define a use outside of a namespace. Consider the following:

namespace{ //default namespace
}

use foo\Bar;

namespace test{
  new Bar(); //error, test\Bar not found
}

After some thoughts it is quite clear that Bar is test\Bar and not foo\Bar inside of the namespace test. But consider
the following example which is not so obvious:

use foo\Bar;
namespace test;
new Bar(); //error, test\Bar not found

The use declaration looks like a normal use declaration at first glance. 
I do not see why we should actually support this "feature" any longer and thus suggest to remove it in PHP 7. Although,
it is not a bug (the use declaration is simply ignored as far as I can tell) I suppose it confuses the user.
Nevertheless, even if we declare it as a "feature" I think it should at least not be a "feature" of the specification of
PHP 7.

Thoughts?

Cheers,
Robert
