Now we no longer have to rely on function pointers intentionally declared without specified argument types. This makes it easier to support functions with floating point parameters or return values as well as functions returning 64-bit values on 32-bit architectures. It also avoids having to explicitly cast strides to ptrdiff_t for example.
