I just mean that using `enum` to define symbols/identifiers sounds
odd, as enum is short for 'enumerate' no?  We wouldn't be enumerating
symbols as that suggests order behind the symbol
identifiers/references, imo :>

Rust's enum/sum value type sounds like a typed union..  the type flag
is just hidden?
