Using operator= is not quite sound in presence of destructors and operator overloading. It's perfectly fine to assume that the left-hand-side of an operator= expression is valid memory, however we're using uninitialized memory here, that may not be the case. Use placement new to properly construct tagged unions. I don't need this with any urgency, but it's the right thing to do in presence of complex types, and the current code seems a bomb waiting to explode :)
