You can't use prototypes to have the compiler check whether
an argument is an integer, or an object of a certain type.
Prototypes are less useful than you might think at first,
and they are sometimes bloody nasty. The following doesn't
do what you want:
sub foo ($$) {....}
my @bar = (1, 2);
foo @bar;
&foo isn't called with two arguments - even
while
@bar has two elements. Remove the prototype,
and it will work as expected.
