I don't think that casting a range of bits as some other arbitrary type "is a bug nobody sees coming".
C++ compilers also warn you that this is likely an issue and will fail to compile if configured to do so. But it will let you do it if you really want to.
That's why I love C++
What do you mean I'm not supposed to add 0x5f3759df to a float casted as a long, bitshifted right by 1?

They know. It's a comment from the code.
