Those are just lists.  There are no named lists, only named hashes,
arrays, and scalars.  Lists by their very nature have no names;
they're just a bunch of values on the stack when it comes down to it.

Calling a list named or unnamed is a misnomer; the former is just
wrong and the latter implies a dichotomy that doesn't exist.
