struct S
{
    private import std.stdio;
}

class Base
{
    private import std.stdio;
}

class Derived : Base
{
    static void print()
    {
        std.stdio.writeln("Derived");
    }
}

void main()
{
    S.std.stdio.writeln("S");
    // Error: Base.std is not a declaration
    Base.std.stdio.writeln("Base");
    // Error: Derived.std is not a declaration
    Derived.std.stdio.writeln("Derived");

    Derived.print();
}

---------

Solution would be to add the disabled code.

----
This is problematic in the following case.
----
module a;

class Base
{
    private import std.algorithm;
}

----
module b;
import a, std.stdio;

class Derived : Base
{
    void foo()
    {
        // 'std' is looked up through Base.std rather than through module level
        // but Derived has no access right to the private import.
        std.stdio.writeln("Derived");
    }
}
