To someone who doesn't know the semantics of reinterpret_cast, perhaps the warning has some value, but for the rest of us what it really says is "Warning! You have used reinterpret_cast!"
Sure, but isn't reinterpret_cast considered bad because of the fact that there is no standard implementation of it?
I'm not sure what you mean. There is a standard implementation of reinterpret_cast.
Really? I thought this was implementation-defined?
Sure, but it is specified that if you reinterpret_cast from T1* to T2*, then reinterpret_cast the resulting T2* back to T1*, you'll get the original value (as long as T2 doesn't have stricter alignment requirements.) Reinterpret_cast is tricky but it is part of the language and it's lame for the compiler to warn when it is used.
