in reply to Re^3: Testing a key creates a hash (ref--)
in thread Why does testing a key create a hash?

False negative: Bless your hash(ref). False positive: Bless you arrayref into "Tie::NotHASH".

You appear to be confusing the return value of ref with the default stringification of a reference.

But be aware that objects can override stringification and non-hash objects can override "hash dereference". This is why Data::Diver mostly uses eval to test for whether something can be used as a hash reference.
