I had a post about this (somewhere, I have no clue what it was called). I'd like something like:

%hash = (
  a => 1,
  b => 2,
  c => $_{a},
  d => $_{b},
);
[download]

Where %_ is a magically bound hash which relates specifically to the hash being defined at the moment, and undergoes run-time magic. (It's not going to happen.)
