{# Okay, so though `enum class` means we can't pollute the namespace with the
enum variants' identifiers, there's no guarantee there isn't some
preprocessor #define lying in wait to collide with us. Using CamelCase
helps, but isn't foolproof (X11/X.h has `#define Success 0`).
So we prefix it. I chose `e` (for `enum`) for the prefix. #}
