Ak. The problem is it thinks it's a declaration. Try 0,typeof(this).a();

yes, it worked (but I guess you'll correct it). I changed it to: interface I { void a(); void b(); } class A : I { void a() { printf("A.a\n"); } void b() { 0,typeof(this).a(); a(); } } class B : A { void a() { printf("B.a\n"); } } int main(char[][] args) { I b = new B(); b.b(); return 0; } it prints: A.a B.a I guess it's the expected result (as much as it displeases me). but it shows another problem with the sintax, (This new problem is not unrelated with the constructores being named "this". There is a big confusion on D with the "this" keyword) "this" should represent the object not something else. on the line "0,typeof(this).a();", "this" clearly does not represent the object. the sintax is not good. the idea is not good.
