in reply to Parameter list wierdness

Try writing your ternary operation like this: 
sub test{
  my $params;
  $params = ref($_[0]) ? shift : {@_};
  print Dumper($params);
}

    aah, that works and it's much nicer. Still think I'm missing something about how the ternary operator works though!

    Thanks, Cxx

      my $value = (if condition?  then this: else this);

      That's about the quickest explanation. Ternary should never be used in void context. See my node Ternary in void context where I cleared up my ternary confusion as well. The ternary operator always returns the value present in its truth branch (for lack of a better term), that's why you shouldn't substitute it for if then constructs.

      an if then construct that warrants a ternary is similar to the following 

      if($some_var eq 'X')
{
    $this_var = 'Run using X format';
}
else
{
    $this_var = 'Run using standard format';
}

      This would equate to the ternary 
      $this_var = ($some_var eq 'X'? 'Run using X format':'Run using standar
+d format');
