Hi basiliscos,
Thanks for your response. Just to clarify: The values I'm looking at are not under my control.
They are normally supposed to be numbers, strings, or objects that stringify to
something useful, like for example Path::Class objects.
Those values will be stringified and used as an argument to an external command,
which is why I make the assumption that references,
which would be stringified to something like "HASH(0x9c5d2d9)",
are probably a mistake on the user's part, and I'd like to provide a warning for those cases.
I've posted my current solution below.
Thanks and Regards,
