sounds good. I will do so, probably next week

Thanks for catching this! Somehow I assumed there would be only one typeinfo implementation and stopped my search too early...

Is having multiple implementations of the same class a common pattern in libcxx? I know there is a similar pattern for `exception_ptr`. Anything else which is similar (so I am aware of it while updating other classes)?
