Such flag warns against NaNs, about large fixed-size variables passed by value, and cases like this that have a different meaning in C and D: int *x, y; And related matters. -- |

I think we added `-transition` specifically to allow fine-grained control of these diagnostics. You can always add support to a build tool like DUB where --fromC would pass in things like a hypothetical "-transition=carrays", "-transition=cpointers", etc. -- |
