Yeah, that's exactly it.
Then why are you doing this
$_ = modify_variable($_)
in all of your examples?

Agree on that, but given other details that I didn't communicate, it is
not quite possible (this is actually a pl/perlu function in postgresql,
the variables I am working on are passed to the function, and their type
is limited by the function definition, so unless I create a composite
type I can't pass them as an array directly).

Perhaps you should describe the full situation then. Without that
information we will not be able to help you very much; we will end up
just shooting in the dark at what we think the problem is.
