 This will define `north`, `east`, `south`, and `west` as constants,
 all of which have type `direction`.
 
+When the enum is is C like, that is none of the variants have
+parameters, it is possible to explicit set the discriminator values to
+an integer value:

+If an explicit discriminator is not specified for a variant, the value

+When an enum is C-like the `as` cast operator can be used to get the
