Well, generally that is true.  If you try to assign a value directly to a
variable that is a number such as:

 $1 = "Hello World";

Then it won't work.  However, due to a somewhat quirky implementation you
can get arund this by doing:

 $a=1;
 $$a = "Hello World";

You can verify that you do indeed have a variable named $1 in your global
symbol table by doing:

 echo $GLOBALS[1];
