Description

There's significant boilerplate associated with using enumerations in arrow, since we need to expose them to the bindings which involves a mapping to/from strings per binding. That's not ideal and we could do better with a metaprogramming utility which provides enum semantics but supports basic reflection (min/max value, number of values, to/from string).
