My personal feeling is that that it adds complexity for very little gain.
If people want an array ref they just wrap the qw() in []'s. It's visually
obvious then that an array ref is being created.

With qa() you now require programmers to remember another fact. Each
little fact on its own isn't a great burden, but perl has accumulated
zillions of such factlets, which cummulatively make perl hard to use.

Now you will have things like

    foo(qw(a b c));
    foo(qa(a b c));

doing two completely different things, and the programmer may get confused.
People already find qw() confusing enough - e.g. whether it parses commas;
now they will have to remember whether qa() obeys the same parsing rules
as qw(). Etc.

Modern art:
    "That's easy, I could have done that!"
    "Ah, but you didn't!"
