hash.rb

# Just an academic snippet for OxRUG's meeting on 
# 12th February 2014. The discussion could be
# about:
# - What does it do (quite pointless otherwise).
# - What are the dangers/drawbacks.
# - How it can be improved.
# - Does it have any function in real life.
# - Etc...

class Hash
  def method_missing(method_name, *args, &block)
    if self.has_key? method_name
      self[method_name]
    else
      super
    end
  end
end

A comment for discussion later...

I think the purpose is to be able to access hash elements via dot notation (because fruit.apple is prettier than fruit[:apple]).

Going back a few months, that was why this emerged: https://gist.github.com/jopotts/7138478
Which leads to Fruit.apple (plus some other bonus features).

Also I think hashery or perhaps facets enable this sort of behaviour, but haven't looked further.
