Nicely summarized! And when cast in this clear fashion, it becomes
obvious (to me, anyway) that Perl is missing some natural bits that
fit right in:

  %x[0,1]      # (0, $x[0], 1, $x[1])
  %x{qw/y z/}  # ('y', $x{y}, 'z', $x{z})

which could then be assigned to other hashes, using in option=>value
parameter lists, etc.

I don't think p5p really needs more flames at this precise moment,
but if it ever starts showing signs of freezing over I now know how
to warm it right up again:-).
