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( ) );
}
?>
