+Genums can also be parsed by their traits by using the `--parsableByTraits=TraitName1,TraitName2` flag. When using this flag code generation will fail if trait values can be parsed into multiple enums; uniqueness is required. Furthermore, there may be edge cases where traits do not parse consistently between various parsers... Durations for example. We will try to fix these in subsequent updates; if you discover any, please file an issue asap.

 ###### Duplicate Values
 
 Duplicated enum values present a small challenge to code; it is not always possible to distinguish between identical values. For example, when turning an enum into string form. In such cases the generator will consistently choose one value as the "primary" value. To force a primary value, mark all others as `Deprecated:`.
