It's not that *you* want to modify `key', it's that `next:' needs a way
to return it. 

In order to return a value, `next:' can either say "return foo", or
you can pass a pointer to (your) `foo' so that it can write to it.

But "return key" isn't an option for the `next:' interface, since it
is already returning the value associated with `key'.
