I want to be sure that if I am expecting you to pass a hash-ref, that I will never accept an array-ref in its place.

Here's one that will make your brane hurt ... 

my $arrayref = [qw(i like pie)];
bless($arrayref, 'HASH');

If I pass $arrayref to a sub that expects a hashref, how will you tell that it is not what you expect?

Dealing with this correctly is on my to-do list for Data::Compare. It will probably involve lots of eval evil.
