hmm, nobody gave you a code example ?

  DB<100> @option{qw/a b c/}=()
 => (undef, undef, undef)
 
  DB<101> exists $option{a}
 => 1                         #true
 
  DB<102> exists $option{d}
 => ""                        #false

but smart-match should be safe as long as you don't forget the quotes.
