Invalidating depending on return

[manuel-rubio]

Could we configure different times for expiration depending on the kind of return?

I mean, if I have the following function:

defmemo request_data, expires: :timer.hours(1) do
  case get("/data") do
    {:ok, %{body: body}} -> {:ok, body}
    {:error, _reason} = error -> error
  end
end

In this situation, maybe the {:error, _reason} isn't a good idea to keep it for one hour and we could keep it only for one minute or 5 seconds.

Maybe it could have something that rewrites the expiration previously to return so we could configure one hour for the OK case and five seconds for the error case.
