read after write is more annoying to process than write before read, can we use `WBR` (or something similar) as opposed to `RAW`?

also maybe we should spell these out instead of using abbreviations? I mostly ask for consistency with other enum classes that are camel case instead of all uppercase (e.g. `None` instead of `NONE`)
