Code:
---
mixin template node() {
    static if (is(this == struct))
        alias typeof(this)* E;
    else
        alias typeof(this) E;  //Line5
    E prev, next;
}
struct list(alias N) {
    N.E head;
    N.E tail;
}
class A {
    mixin node L1;  //Line13
    mixin node L2;  //Line14
}
list!(A.L1) l1;  //Line16
list!(A.L2) l2;  //Line17
---

Output:
---
test.d(5): Error: this is not in a class or struct scope
test.d(5): Error: 'this' is only defined in non-static member functions, not
node!()
test.d(13): Error: mixin test.node!() error instantiating
test.d(16): Error: list!(L1) is used as a type
test.d(5): Error: this is not in a class or struct scope
test.d(5): Error: 'this' is only defined in non-static member functions, not
node!()
test.d(14): Error: mixin test.node!() error instantiating
test.d(17): Error: list!(L2) is used as a type
