Would be nice to NOT know whether $stranger is an "elf type-of thief" or "thief type-of elf" and be able to do this: 
# ".?" means "call if the obj CAN the method" acc. to Apoc12
$stranger.?steal;
$stranger.?shoot_arrows;

and expect DWIMming (doing both things in both cases). That's the whole point of polymorphism, is it not? :)

Update: upgrade perl5 syntax to perl6 (Apoc12).
