As already noted in this thread, using globals is highly discouraged and as such it does not make
sense to add any further functionality improving their use.

Also (you say this yourself) you can use $GLOBALS. I don't understand why you don't want
to use it. Language features aren't added simply because someone says "Hey, I want to
access globals in one expression, but I don't want to use $GLOBALs, please add a feature that
is fully equivalent but uses a different syntax".

But even with the constraint of not using $GLOBALS you can easily build a function that would do
something equivalent:

    function getGlobal($name) {
        global $$name;
        return $$name;
    }

    $foo = getGlobal('foo');

Marking this as Wontfix.

My solution would be to introduce global as a scope identifier, so you could use 
it as:

global::$object = new stdClass;
global::$object->test = 'This is just a test';

function test()
{
    return global::$object->test;
}


Although I do believe globals are evil and static class variables should be used 
at all times, this is a neat addition to avoid the very ugly and unclear global 
keyword.

As it is now, you have to define a variable as global for it to resolve and act on 
the global variable. This makes code hard to read as it is not directly visible 
that this is the case. The above syntax would solve this problem.

Imagine I have unset the, ( $GLOBALS )..
To access a 'global' object into the function, first must be called trowght global..

function test()
{
    global $object;
    return $object->some_method( );
}

I wonder if is posible to use (in the future :P) the 'global' like other language
structures.. Ex:

function test()
{
    return( global $object->some_method( ) );
}

I know ... you will ask me why not use the namespaces, reflections, references, traits, or
whatever.. but .. its not the point ...

In the first line I just wrote: "Imagine I have unset the ($GLOBALS)"

for some reason.. (is ugly, security, memory consumption, the host provider doesn't allow) or
who knows why ...

I know how it works for now but the question is not about how to use "$GLOBALS".

anyway, thanks for the time spent to answer

For now:
<?php
function test()
{
    return( $GLOBALS['object']->some_method( ) );
}
?>
