           Summary: Nested class can't access var in outer function scope,
                    if nested in class

The nested class can refer to members of the enclosing class, but not variables
in the enclosing function.

I assume the problem is that the context pointer of the anonymous class nested
within Foo's constructor refers to the Foo instance, and not to the stack-frame
of the constructor.

Whether intentional or not, the compiler accepts the program and generates
buggy code.

--- Test case ---

import std.stdio;

void foo()
{
    int x = 42;

    new class Object
    {
        this() { writef("%s\n", x); }
    };
}

class Foo
{
    this()
    {
        int x = 42;

        new class Object
        {
            this() { writef("%s\n", x); }
            // Can't access 'x'. Any members of Foo are accessible, however.   
        };
    }
}

void main()
{
    foo(); // prints 42

    new Foo(); // prints garbage integer (e.g. 0, on my system.)
}
