Agreed, if it would return a reference to a temporary, I would have a
severe problem. But it was intended to do anything *but* create a
temporary. My tests showed that the static_cast< static_cast<
const_cast< > > > sequence produces an identical assembler output than
the reinterpret_cast for the operator (gcc 3.2) and I don't see any
reason why a temporary should/could be created.
