Sorry for posting it so late, but I would like to clarify the things
in my head. I hope a final post with compiled definitions and final
decisions is useful for other people interested in this new
functionality.


1 - The official namespace support will not use curly braces? Never or
can be in the future?

IMHO, I am +1 in this subject. A quick explanation why I am a brace's
fan. How do you declare a class?

<?php
class Foo;

public $bar = 0;

static public function test() { echo "Here Mommy!!" }

Or...

<?php

class Foo {
  public $bar = 0;
  static public function test() { echo "Here Mommy!!" }
}


I suggest to get things standard-ized. If a class uses braces,
functions uses braces, why not use braces for namespaces...?

I read in previous messages (I think from Dmitry) that you want to use
one namespace per file (and allow same namespace in multiple files),
but why should PHP control it? Keep things flexible and let the PHP
programmer decide what should he do.
If he wants to define a global function and a namespace in a single
file, it's up to him decide to do it or not.
I'll give you an example... PHP Doctrine package has a lot of files,
hundreds... there is a way to compile it in a single file, to save
some memory usage for including these files. Including a single file
is better than include hundreds, as you may know.
If you restrict it to a single namespace per file, Doctrine will load
the hundreds, and not a single one anymore. So, any effort to compile
scripts into a single file will be useless. Lukas Smith can provide
more in this subject about how Doctrine works, but I just want to
illustrate that you'll break some functionalities that current exists.


I have another questions regarding commom namespace usage... I am
interested to use, as most of all developers.


2 - Overwrite will be implemented?
Something like: overwrite function strlen( ... ) { ... }


3 - How will PHP behavior on a situation that you have a naming conflict?

Something like...

<?php
class Bar { ... }

<?php
namespace Foo {
  class Bar { ... }
}

<?php
import Foo;

$b = new Bar();


4 - Will namespaces support anything else than functions and classes
(like constants, for example)?



Thanks in advance...


Best regards,
