$ dmd test.d 
entity.(fld)
Internal error: e2ir.c 688
Comment 1 Andrej Mitrovic 2012-03-04 11:18:57 UTC 
Slightly more reduced:

class Query(string queryText)
{
    class Entity
    {
        void[] buf;

        class fld(T, string varName)
        {
            T opCall()
            {
                return cast(T)buf;
            }
        }
    }
    Entity e;
}

void main()
{
    scope query = new Query!"SELECT ONLY_NEEDED_COLUMNS";
    auto entity = query.e;
    auto email_addy = entity.fld!(char, "email")();
}
Comment 2 Trass3r 2012-03-04 13:36:23 UTC 
And more:

class Entity
{
  class fld()
  {
    char t;
  }
}
 
void main()
{
    Entity entity;
    auto email_addy = entity.fld!().t;
}

Comment 4 Denis Shelomovskii 2013-10-14 03:18:06 UTC 
It can be templated `class`, `struct`, or `union`, with function or field.

Testcase from Issue 7701:
---
struct S {
    struct S2 (T) {
        void fn () {}
    }
}

void main () {
    S s;
    s.S2!int.fn();
}
---

Also now internal error is: e2ir.c 780
