I was reading through some module code the other day and I remember seeing a subroutine where it was called like: 
sub dothis ($:$$$) {
           ## rest of the code
}

I've seen in other languages (like vb I think) where subroutines are called in such a manner, whereas in perl its generally done like 
sub dothis {
          my ($this, $that) = @_;
          ## rest of the code
}

Does anyone know what this $:$$$ means in Perl?
