sub foo {
  my $self=shift;
  if (@_==1) {
    // do something with single arg
  } elsif (@_==2) {
    // do something with two args
  }
}

Point is that in a language like perl we can a) simulate the behaviour of java, b) we can provide behaviour that java plain and simple cant provide.

Incidentally what do we do with 

foo(@bar);

[download]

Which version of foo should be called? Should the langauge simulate the if that i put inside the sub above? If so what do you do when you have a situation that doesnt make sense? For instance if @bar contains 3 vars. What should it do? Call the var version and ignore the third? Die?
