# If you wanted to make a constructor that did some extra stuff
# on the newly created object before giving it back to you
# you might be tempted to write it like you would in Ruby:

class Modal
  @load: ->
    modal = new this
    modal.load
    modal

# This is a module that provides two methods, `expose` and `let`, which
# allow you to cleanly and clearly define lazily-evaluated, memoized
# values that you can use anywhere in your controllers and views. It's
# very similar to the decent_exposure[1] gem, but it works more simply
# (and doesn't have a default action when you don't pass a block to
# #expose, to keep things very very simple).
#
# You will want to mix this into ApplicationController.
#

Semicolons

Don't write them; they'll be inserted automatically.

Functions

Replace function () { ... } with ->.

# In Ruby 1.8.6, there's a bug in YAML that is revealed when you
# serialize and then deserialize a large YAML::Omap. If you look
# at the generated YAML, it looks like every so often, instead
# of an object showing up in the YAML file, the object is skipped
# and another a reference to another object shows up. This does
# not seem to happen with an Array of values, or an Array of Arrays,
# or an Array of Hashes, or a Hash. This behavior was fixed in 1.8.7.
