Though, it should (might?) be possible to implemetn something like
Hash's or Array's

hash[key]
array[index]

index methods for plain old object instances, too.

I haven't seen such an implementation, though, and my C and Java fu are
too weak to make sense of JRuby or CRuby.

Maybe Rubinius is a starting point, since it supposedly implement core
classes in Ruby.
