+    # Usage:
+    #
+    #   require 'factory_girl/syntax/sham'
+    #
+    #   Sham.email {|n| "somebody#{n}@example.com" }
+    #

+    #     factory.email { Sham.email }
+    #   end
+    #
+    # Note that you can also use Faker, but it is recommended that you simply
+    # use a sequence as in the above example, as factory_girl does not provide
+    # protection against duplication in randomized sequences, and a randomized
+    # value does not provide any tangible benefits over an ascending sequence.
