I noticed a attr_access.internal_p which has the following comment in
attribs.c:
/* Forms containing the square bracket are internal-only
(not specified by an attribute declaration), and used
for various forms of array and VLA parameters. */
That should be a good differentiator right? It fixes the motivating case here.
This is what I'm testing a bit more extensively.
