Re^2: How to differentiate hash reference and object reference?

But ->isa return's true if the argument is in the package's @ISA array. ref( $obj ) does something different. I think UNIVERSAL may be more the way to go.

No, `isa()` returns true if whatever method `isa()` is for the invocant it returns true. If I wrote an object and overrode `isa()` to return true based on a the phase of the moon, that's what it would do. That's probably unwise code to write, but the purpose of having `isa()` be a method is so that classes can override it when it makes sense to do so.	[reply] [d/l] [select]

Yes, but I was more on to what the OP wanted to achieve with it. Therefore the suggestion of UNIVERSAL::isa. Ordinary morality is for ordinary people. -- Aleister Crowley	[reply]
