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. -- Alain Williams Linux/GNU Consultant - Mail systems, Web sites, Networking, Programmer, IT Lecturer. +44 (0) 787 668 0256 http://www.phcomp.co.uk/ Parliament Hill Computers Ltd.
