When the elaborator doesn't provide us with any `CompletionInfo`, we currently provide no completions whatsoever. But in many cases, we can still provide some helpful identifier completions without elaborator information. This PR adds a fallback mode for this situation. There is more potential here, but this should be a good start. In principle, this issue alleviates #5172 (since we now provide completions in these contexts). I'll leave it up to an elaboration maintainer whether we also want to ensure that the completion infos are provided correctly in these cases. |
