Subject: variable variables in global - bug?
From: greg@chiaraquartet.net (Greg Beaver)

Hi,

It was brought to my attention that this code is legal in PHP 4:

function foo($param = 'test')
{
     global $$param;
     echo $$param;
}

$test = 'bar';
foo(); // prints bar

Is this a feature or a bug? (Should we support this syntax in 
phpDocumentor, or might it change in php 5?)

Greg
