But you have to consider this:

   b = 9,5   # => [9,5]

so "[9,5] without a []", on the rhs, gets turned into an array.  I
know it sounds like I'm putting in an extra step... but it really is
consistent in terms of the behavior of * itself.

What would that mean, though?  Or, to put it another way, what could
you possibly do with *a on its own?
