Description:
------------
The backslash namespace separator was introduced in 2008 http://news.php.net/php.internals/41374

Would it be possible to consider using dots inside strings. Eg:


```
namespace "my.package";
use "some.package.class";
```

How difficult would it be for the interpreter to parse this line of code? For me, it the most modern and clean solution. And it looks much better, doesn't it?


Expected result:
----------------
```
namespace "my.package";
use "some.package.class";
```

Actual result:
--------------
```
namespace my\package;
use some\package\class;
```
