Good suggestion.

Partially solved via #2331. The reflection API is large, and it would be difficult to ensure that all the cases are covered, so, given that simple examples work at least, it's probably better to roll out the partial solution and fix other issues as they surface.

I'm closing this issue for now, but feel free to reopen it in case some other false positives arise.
