SymbolicHash provides an extension of Hash, but one that only supports keys that are symbols. This has been done in an effort to prevent the case where both a string key and a symbol key are set on the same hash, and espcially for dealing with this particular case when convert the hash to a string.

Example

  hash = Relax::SymbolicHash.new
  hash[:one] = 1
  hash['one'] = 2
  puts hash[:one] # => 2
