The loop control variable (the variable through whichyou access the
values in the array you loop over) is actualy an ALIAS to the
list/array value, not a copy. This means that if you change the
content of the variable you are changing the contents of the array.
But of course this time the items of the array (well, actually list. It's
better to distinguish the two ) are constants. Thus you cannot
change them. Thus you canot assign to $_. you have to copy the
value to a different variable first.
