it is very old syntax (i think even back to perl4). the x operator 
duplicates the left side by the count on the right side. if the left is 
a scalar, the duplicates are merged into a single scalar. if the left 
side is in (), it is assumed to be a list and the duplicates are merged 
into a list. so what you see is a list of '?' duplicated into the list 
you got. you can read more about x in perldoc perlop.
