A handful of handy casts.
template <class To, class From> To tl::bit_cast (From const& from)
Casts the bit representation of from to a To. Use this instead of type punning through a union or reinterpret_cast. Essentially does: :
To to;
std::memcpy(&to, &from, sizeof(to));template <class E> auto underlying_cast (E e)
Casts an enumerator value to its underlying type.
SFINAE-friendly.
