Let's use bitwise_cast here too.

Why?
My preference of casting is:
1. static_cast
2. bitwise_cast
3. reinterpret_cast

I just wasn't thinking correctly.  I guess static_cast does a compile time type check, and hence, is preferable to bitwise_cast which only does a size check.  I withdraw my comment.
