> This compiles, but shouldn't:
You add declarations to namespace std which is undefined behaviour, so any
result is valid.
The DR looks wrong to me, the point of treating std as an associated namespace
is that std::begin and std::end will be found for user-defined containers, not
just the standard containers. I don't know why core decided to change that.
