'namespace-internal' internal keyword, a cross between private and internal that limits access to the same namespace

[e8-MattLoidolt]

Request for an accessibility keyword that restricts the access to the function/variable to only items in the same namespace.

For example:

namespace A {
   public class myClass {
      public string myPublicValue;
      namespace-internal string myNamespaceInternalValue;
   }
}

namespace B {
   public class testClass {
      public static void workWithMyClass() {
         myClass foo = new myClass();
         foo.myPublicValue = "test 1"; // allowed
         foo.myNamespaceInternalValue = "test 2"; // error: 'myNamespaceInternalValue' is inaccessible due to its protection level
      }
   }
}

In a organization with several teams working on a single monolith application, this allows for teams to control access between the namespaces, when each team has their own namespace(s)
