It's important that a new language have a way to interface to existing
hardware and software. So there has to be something that maps to C arrays
and pointers (and the equivalent for hardware). But that doesn't necessarily
have to be something that is used outside of interfacing. An Ada example is
Unchecked_Unions -- they exist for interfacing but shouldn't be used
otherwise. A fixed vector type and a raw general access type would do the
trick, but those could be something that are almost never used outside of
interfacing packages.
