Just to be thorough,

my ($one, $two) = _@;

works once, but ignores the side effect of shift (removing the arguments from the @_ array).

As Marshall says, using a reference to an array would be the best way to deal with a lot of parameters, but if you wanted to, say, process two at a time, you could do

while (my ($one,$two) = splice @_, 0, 2) {
    #do something
}

(you'll get an uninitialized value warning if you supply an odd number of parameters)
