Well, I've done it that way if I'm willing to limit myself to pointers or ints up to a pointer size, but that doesn't work with floats or doubles, for instance.

Well, I've done it that way if I'm willing to limit myself to pointers or ints up to a pointer size, but that doesn't work with floats or doubles, for instance. Ergonomically, I have tended to start using _Generic for static type checking where possible, and that pushes me more toward to avoiding arrays in types for this kind of thing.
