Based on feedback from Nikita we've made three last changes to Naming Things(tm).

1) IterableEnum is back to "UnitEnum", which is the superset of Pure enums and Backed enums.  
2) The reflection classes were renamed accordingly.
3) We clarified that tryFrom() will behave "as you'd expect" if passed an incorrect type, given strong vs weak mode.

And a few other inconsequential word tightenings.

Baring any other revelations, voting starts tomorrow.
