I think, the correct diagnostic it your case should be "const constructor is not defined". Also const system gives you a chance to design const-correct code, it doesn't necessarily make it simple. Design takes a lot of effort. That said, yes, you can get stuck unable to solve your problem with your skills. Though I don't think const-correct code is a must: I didn't see a single bug caused by lack of const. Const-correct code doesn't buy you a lot, really.

btw, the inout solution is not quite right thing there, Steven proposed the correct design: const opSlice should return Slice!const(T), not const(Slice!T).
