in reply to Is there a way to find out what kind of ref an object is?

the first thing that comes to mind is:
eval { keys %$ref } ; print "its a hash" unless $@;

    use overload '%{}'=>sub{{}}; sub new { bless [] } $ref = new(); eval { keys %$ref } ; print "is it a hash?" unless $@;
      That'd be the correct answer most of the time - if an object promises says it "can do" a hash interface, its up to everyone but the most sneaky to go by that.
