JS-flavored hashes in Ruby

I’ve become frustrated with Ruby’s syntax for hashes.

hash = {:foo => 'bar'} # not a fan
=> {:foo=>"bar"}
hash[:foo]
=> "bar"

Here’s a (non-recommended) way to make it look better by extending the Hash class directly:

class Hash
  def method_missing(m)
    k = m.to_sym
    return self[k] if self.has_key? k
    super
  end
end

This allows the following syntax:

hash = {foo: 'bar'}
=> {:foo=>"bar"}
hash.foo
=> "bar"
