With the recent patch this doesn't compile, is this expected?


struct Foo {
    int x;
    alias x opDollar;
    int opIndex(int k) { return x * k; }
}
void main() {
    Foo f = Foo(7);
    int x = f[$ - 5]; // Error: undefined identifier __dollar
    assert(x == 2 * 7);
}

Yes, it checks that opDollar is either a function or a template function.

Poor error message though. All the overloaded operators have bad errors:

struct S {
   void x() {}
   alias x opUnary;
}

void main() {
    S a;
    a = -a;
}

test.d(9): Error: a.x isn't a template

struct S {
   int x;
   alias x opUnary;
}

void main() {
    S a;
    a = -a;
}
test.d(9): Error: 'a' is not of arithmetic type, it is a S
