d的模块级封装,这应工作

如下代码:

module a;

class Foo
{
    private:
    int _c;
}

import b;
void handle(Bar child)
{
  child._c += child.c;
}
//---------
module b;

import a;

class Bar : Foo
{
    public:
    int c;

    this(int c)
    {
        this.c = c;
    }
}

//---------
module main;

import a;
import b;

void main()
{
    auto bar = new Bar(30);
    handle(bar);
}

应该允许在a模块中,

void handle(Bar child)
{
  child._c += child.c;//应允许可访问_c
}

毕竟,你是标榜自己模块级封装.
