In tonight's meeting I tried, and failed, to show how to create a Struct with a custom method. ~~Turns out, you can't do that. But you can use Class.new to accomplish this.~~ UPDATE: You can do this. I don't remember what syntax I was trying before, but in 1.9.3 you can successfully pass a block to Struct.new; though this isn't documented.

The end result is the same:

A new Class object
Default initialize handling the attributes
attr_accessor methods defined for those attributes

Big thanks to @steveklabnik for his two posts which inspired me to try to show this horribleness (that's a reflection on my silliness, not Steve):

So recently I was looking for a way to do a comparison on a String with either another String or a Regexp. Looking online didn't yield much help, most discussions on equality focused on ==, eql?, equal?. None of which would satisfy the requirement. So I was left with this code:

def matches(compare_with)
  if compare_with.is_a?(Regexp)
    @data_string =~ compare_with
 else

	# The points are stored in a nested hash
	# {
	# "bounds"=> {
	# "northeast"=>{"lat"=>39.0464399, "lng"=>-76.9836289},
	# "southwest"=>{"lat"=>38.995162, "lng"=>-77.033157}
	# },
	# }
	# We just want the values, as an array:
	# [north_lat, east_lng, south_lat, west_lng]
	def extract_bounding_box_version1

	module Fetcher
	class Base
	# ... other code ...

	def uri
	@cue
	end

	def options
	{}

	module Fetcher
	class BasicTraffic < Base
	add_fetcher_options after: :count_severe_incidents

	def self.inherited( subclass )
	subclass.add_fetcher_options after: :count_severe_incidents
	super
	end

	private

	require "money"

	class Decorator < BasicObject
	undef_method :==

	def initialize(component)
	@component = component
	end

	def method_missing(name, *args, &block)

	my_array = %w[test one two three]

	# Inject takes the value of the block and passes it along
	# This often causes un-intended errors
	my_array.inject({}) do \|transformed, word\|
	puts transformed
	transformed[word] = word.capitalize
	end
	# Output:
	# {}
