interface_final_test.d(22): Error: function interface_final_test.A.foo (int a, int b) is not callable using argument types (A,int,int) interface_final_test.d(22): Error: expected 2 arguments, not 3 for non-variadic function type int(int a, int b)

Why do I need to write a.I.foo instead of a.foo to call the final method of the interface ?

Thank you, Joshua

I can't comment on the behaviour, but you may find this workaround useful:

class A : I {
alias I.foo foo;
int foo(int a, int b) {
return a*b;
}
}
