I think this is not the case where we’re dealing with ill-formed Decl-contexts; it is that the caller site doesn't respect the assumption that “the surrounding Decl for a TTPD shall be a file-scope decl”.

I think I’ve already done that? (I have updated the patch to address it and that looks fine then), I’m just unsure if the removal for such assumption is appropriate. (or maybe i’m misreading your points? Should I change the call sites instead?)
