If this were to happen:
- I would prefer much shorter elegant constants.
- A constant for suppressing warnings thrown by include without
suppressing warnings/errors by the actual file -- I think we can all
agree @include is counter productive since it does much more that
suppress warnings thrown by include (even parse errors!).
