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.

std::bit_cast is

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