The check I had in mind though ostensibly could be in-tree, if you guys were interested. Though now that I think about it more, I think it would need `isTriviallyDestructible` rather than `isTrivially`. It basically detects whether there is an assignment of the form ``` <trivialy_destructible_type> = <destructible_type>; ``` which is frequently (but not always) dubious. The canonical example here would be: ``` std::string Get(); std::string_view sv; sv = Get(); // dangling pointer ``` which results in a dangling pointer. `-Wdangling` would catch the obvious candidates annotated with `lifetimebound`, but this check would surface things that might not be annotated.
