  | @ means everything or nothing. Unbound variable errors should not apply to 
it.

I know nothing about namerefs and arrays and stuff like that,
but did you consider the possibility that after

        array=()

then

        array[@]

is nothing, and so

        __ref=array[@]

is just

        __ref=

and consequently ${!__ref} is attempting to use '' as the name of a
variable?
