C++ doesn't have CTFE. CTFE is why it really matters in D. If you're dealing with a compile-time constant, it uses CTFE. If you're dealing with a runtime constant, it doesn't. So, you need to be explicit. Personally, I don't really care about using enum the way it is. Having enums freely converting to and from their base type is more of a concern, though I'm not sure how much that really does or doesn't matter. It's quite clear when an enum is used as a manifest constant and when it's used as an enum, so I don't really see a problem with the way it is, though I can see why someone wouldn't like it. - Jonathan M Davis
