Probably because you never really want to find out whether some value is
in a hash, you just want to know whether a key has a value to look up. If
you need to know whether a value is in a hash, it'd be good to rethink
your design.
That and it's stupid to see if an index is in an array. You can just say
$ind < @array. So, it DWIMs. In my opinion, it does so very well.
