It occurs to me that bash should print a warning when you attempt something

declare -n foo=bar
declare -i foo

The manual explicitly lays this out as something you can do:
Sorry, you're right. This indeed changes the attributes on the target
variable,
if you're applying it to an already-declared nameref. It's trying to give
thenameref variable itself the integer attribute that is the problem.
So the question is now whether to disallow `declare -in foo' (or
`declare -in foo=bar') and make it a usage error, print a warning that
it will be ineffective, or simply let it be ineffective, as it is now.
