I forgot how easy it was to invoke C++ ODR-based undefined behaviour when
using nested namespaces! :o
header file #1 :-
namespace parent
{
class foo
{
};
}
header file #2 :-
namespace parent::child
{
class foo
{
};
}
header file #3 :-
namepsace parent::child
{
class bar
{
foo m; // which foo this is depends on header file
inclusion for this translation unit! :o
};
}

And what's your practical problem with that ?
