I'm not sure what you're getting at but const bool z = (const bool)((int8_t)2); Is perfectly valid C++.

  That's a conversion, not the same. The naive equivalent to transmute would be int8_t x = 2; bool y = *reinterpret_cast<bool *>(&x); But reinterpret_cast isn't valid in a constexpr scope.

    My 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.

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