How is passing a void* to PetscObject/PetscContainer different from passing it to SNES? Also, would you have different types for every callback or would you reuse? If reusing, would the interface require casting the function pointers to void(*)(void) instead of what is currently type-safe for most function pointers? This feels like less rather than more type safety. Agree on other points.
