Sure. That's what [global] gets you.

Anyway, [global] is a special case of [upvar] and just basically has 
default arguments. Complaining you have to use [global] in Tcl is silly.

PHP has no [upvar], and PHP has "superglobals" which you don't have to 
redeclare inside procedures, so it's just a mess.
