I never did understand *why* variables were not namespaced.
However, since 5.3 has been out for a while it might make things difficult to
make them - would break BC, unless the following was adopted -- something that
would really make me happy:
namespace foo;
var $bar; // Creates the variable $\foo\bar;
I *still* really want to have something like perl's ''use strict''. If 'var'
is used outside of a function then ''use strict'' becomes switched on, the
way to access a global variable would be to use the namespace \ - first
declare it:
var $\globalName;
Note that the 'global' keyword would still be used in functions:
function blob()
{
global $\globalName; // Import from $GLOBALS
global $bar; // Import from current namespace
}
The above might even be extended:
namespace foo;
public $bar; // Creates a variable $\foo\bar this is available to
code outside the namespace
private $fred; // Creates $\foo\fred that cannot be accessed by code
outside the namespace
Variables in a namespace would not appear in $GLOBALS.
