Proposing new syntax for zero-cost unwrapping options/results

I’m not a fan of let? syntax. Mixing text and symbols just looks complicated

I propose using maybe instead.

Then the examples would look like this

/* returns: string => promise<result<decodedUser, 'errors>> */
let getUser = async (id) => {
  /* if fetchUser returns Error e, the function returns Error e here. Same for all other `maybe` */
  maybe Ok(user) = await fetchUser(id)
  maybe Ok(decodedUser) = decodeUser(user)
  Console.log(`Got user ${decodedUser.name}!`)
  maybe Ok() = await ensureUserActive(decodedUser)
  Ok(decodedUser)
}

I like it because maybe is already a well known convention with optionals. e.g. type maybeUser = option<user>

This might be naive, I’m not much of a language architect. Let me know what you think
