Although argv acts like a local, it's actually a global special, so
you always get the special behavior even when accessing through a
nameref.

I thought I'd mentioned this somewhere in the doc but perhaps not.

Underneath, argv ends up being a pointer into the C stack, so there's
no way to get a reference to it from a called function up to the
caller.
