flag hashable
  description:
    You can disable the use of the `hashable` package using `-f-hashable`.
    .
    Disabling this is an unsupported configuration, but it may be useful for accelerating builds in sandboxes for expert users.
    .
    If disabled we will not supply an instance of `Hashable`
