I generally find it hard to construct some sentences that start with "I wish, ..."
Example:
(Background:) Due to an incomplete technical documentation, we chose the wrong path, and ran into an unforeseen limitation. What's the correct way to state my frustration?
- I wish, the documentation would warn about that limitation.
- I wish, the documentation had warned about that limitation.
- I wish, the documentation would have warned about that limitation.
- I wish, the documentation warned about that limitation.
- I would wish, that the documentation warns about that limitation.
- ...
