Is it possible in ruby to make use of constructs that correspond to
the following Perl constructs? ...

  $array[1][2][3] = 'whatever';   # multidimensional array

  $hash{'a'}{'b'} = 'something';  # multidimensional hash

I know that I can create classes in ruby which encapsulate this
behavior, but before I re-invent the wheel, I'd like to know if anyone
has already come up with things like this in ruby.

Thanks in advance.
