Global Namespaces
Just like in C++ and C#, Jancy features support for global namespaces. It is OK to open a nested namespace in one go; it is also OK to open and close the same namespace multiple times for adding new elements.
namespace a.b.c {
namespace d {
} // namespace a.b.c.d
} // namespace a.b.c
namespace a.b.c.d {
} // namespace a.b.c.d
