Has there been any discussion about adding WARNING pragmas to `Prelude.undefined` and `Prelude.error`, as done in some custom preludes?
I suppose this hasn't been done yet to avoid breaking existing code which makes "legitimate" use of those helpers?
`undefined` is useful when you want to check types in, e.g. ghcid, without writing a function in full. With -Wall on, that Warning could become annoying fast.
