[nem-en] About opening namespace

[Kamil Skalski]

>    Whether should work the following code?

I don't think so... By specifying 'using A' you just say that you want
to have classes with names A.* available. Every using declaration is
rooted in the currently opened namespace:

using A;   ///  root.A

namespace B {
  using C;  // opens  root.C  and B.C
}

The "nesting" logic of using that you propose is a bit strange,
especially that by looking at code it is not easily visible, that

using A;
using B;
...

would mean:

using A {
  using root.B
  using A.B;
  ...
}


And most importantly - it is quite a large breaking change, which is
moreover not consistent with C#'s behaviour.
