Update:Ignore the rest of this node - as johngg points out, below - this code is equivalent to his assignTo sub.

If you like, you could add what "Anon Monk" implied was possible: 

sub Modify_param_array{
   print qq{In Modify_param_array - change @_\n};
   @_ = qw[New contents. The caller never sees this];
}
