I think such enhancement of warnings effectively requires size_t to be some kind of "strong typedef", and the "strength" should be generated from sizeof, alignof, etc.. Perhaps the built-in operator- between pointers also needs to generate such "strength" for the purpose of ptrdiff_t. ^ permalink raw reply [flat|nested] 2+ messages in thread
