That may well be, although as I write I can't recollect having seen that 
anywhere; so I don't use that form. However I have been caught by something 
like the following:


function yes ($a)
     global $x;
     if  ($a)  $x = "yes\n";

first (true);

echo $x;


but I haven't looked into $GLOBALS enough to know whether using them instead 
would have saved my bacon.
