Facet's has Association which gives one something quite like that.

  [ :a >> 1, :b >> 2 ]

Of course it does take over the #>> operator, so it can't be used
inside any class that defines it. But that's not a big deal. It just
means you can't _extend_ the following classes with code that uses an
Association.

  Bignum
  Fixnum
  Date
  IPAddr
  Process::Status
  
T.
