Sorry that's wrong, should be:
struct Foo {
    auto opIn_r(int i) { return 1; }
}

And then you get:
test.d(25): Error: function test.Foo.opIn_r (int i) is not callable
using argument types (string)
test.d(25): Error: cannot implicitly convert expression ("") of type
string to int

which much better than Bar's error message.
