Right, okay.  Well the current approach uses method_missing.

I say we just go with Hash and then have a specific option for using
HashWithIndifferentAccess.  I like this alot better, because it
means you can just set the option and things work just like 1.5 and
backwards.

  Camping.goes :Tepee
  Tepee.include HashWithIndifferentAccess
  Tepee.include Markaby

Err... or something.

Let's use Strings for Hash keys, since HWIA uses Strings internally,
which is likely to be nicer for ActiveRecord and because of symbol 
memory concerns, lastly.
