Overview

IndifferentVariableHash::Hash extends Hash to be ‘indifferent’

‘Indifferent’ has a few different meanings and needs to be better defined.

This is custom in 2 major ways:

* All keys will be stringified (so foo[:hi] and foo['hi'] are the same)
* Sending messages are translated into keys, eg. foo.hi returns foo['hi']
