Test for String Equality

In Rails, there is an nice and easy interface that can be used to check a string for equality.

To do this, you can use the ActiveSupport::StringInquirer object. Simply initialize it with a string value, like so:

string = ActiveSupport::StringInquirer.new("vanilla")

and now we can just call string#vanilla? to check for equality

string.vanilla?
=> true

string.chocolate?
=> false

Fun fact:
This is how you are able to do Rails.env.production?
