bool y = *reinterpret_cast<bool *>(&x);
But reinterpret_cast isn't valid in a constexpr scope.
- poppadom1982 6mo agoMy point is, in your exact example both reinterpret_cast and C-style casts have the exact same behavior, making the example bad. If you want to showcase a deficiency of C++, it would make sense to pick something where the difference between cast types actually matters.

- debugnik 6mo agoOh cool, and it behaves like memcpy, not like pointer aliasing! I'm stuck with C++14 at work so I missed that one.
