Another reduced case:

class Foo {
  class FooInner {}
}
class Bar: Foo {
  byte foo;
  class BarInner(T): Foo.FooInner {
    byte zoo() {
      return foo;
    }
  }
  alias BarInnerThis = BarInner!Bar;
}

$ dmd -c test.d
test.d(8): Error: need 'this' for 'foo' of type 'byte'

Analogous case that does not work in dmd 2.086.0, but works in 2.085.0:

class Base
{
    class BaseInner {}
}

final class Derived: Base
{
    bool someMethod() { return false; }

    final class DerivedInner: BaseInner
    {
         void func()
         {
             pragma(msg, typeof(this.outer)); // prints "Derived"
             someMethod();
         }
    }
}

void main() {}


compiler output:
Derived
onlineapp.d(17): Error: this for someMethod needs to be type Derived not type
onlineapp.Base

Shouldn't this bug be marked now as a regression? Checking the code in the previous comment:

Up to      2.067.1: Success with output: Base
2.068.2 to 2.085.1: Success with output: Derived
Since      2.086.0: Failure with output:
-----
Derived
onlineapp.d(16): Error: `this` for `someMethod` needs to be type `Derived` not
type `onlineapp.Base`

(In reply to Puneet Goel from comment #0)
> This is one of the corner cases that I could reduce.

-       return (zoo).frop();
+       return frop(zoo);

Note with the above change it compiles successfully.

These actually appear to be three separate issues.
