Contextual Monks,

If I want a subroutine that works with strings to have the ability be called in a scalar or void content, either:

v: do_something_to(\$this_var);
s: my $this_var = do_something_to($that_var);

Is this the best (only) approach? 
sub name {
  my ($arg) = @_;
  if (ref $arg) {
    $$arg = 'x';
    return;
  }
  else {
    return 'x';
  }
}
