Nameof operator

I can understand this. Accessing by keys rarely happens in pure ReScript code, but is useful when interacting with external JS codes.

I used this pattenrs a lot

type key =
  | @as("preferred_language") PreferredLanguage
  | @as("preferred_timezone") PreferredTimeZone

@genType
module Key = {
  let \"PreferredLanguage" = PreferredLanguage
  let \"PreferredTimeZone" = PreferredTimeZone
}

Used it for building DTOs

There may some community PPXs exist already. e.g. GitHub - Astrocoders/lenses-ppx: GADT lenses

But generalizing it with using PPX or Proxies seems like an overkill solution. What it really need is more of a simple record ↔ dict converter.
