           Summary: opDot() should work as expected with operator
                    overloading.
           Product: D
           Version: 2.018
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: minor
          Priority: P3
         Component: DMD
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: dsimcha@yahoo.com


struct Foo {
    uint i;

    Foo opAdd(uint input) {
        return Foo(i + input);
    }
}

struct Bar {
    Foo foo;

    Foo opDot() {
        return foo;
    }
}

void main() {
    Bar bar;
    auto result = bar.opAdd(5);  //Works.
    auto result2 = bar + 5;  //Compile time error:  test.d|22|Error:
incompatible types for ((bar) + (5)): 'Bar' and 'int'|


}

IMHO, this behavior is incorrect. Operator overloading is supposed to be semantically equivalent to calling the method with the overload name, i.e. a + b is supposed to be the exact semantic equivalent of a.opAdd(b) if a and b are class or struct objects with overloaded opAdd.  In this case, it clearly isn't.

Is opDot() going to be deprecated once alias this is better-debugged?  I see no reason why it shouldn't be.  If so, I'll mark this as wontfix.

I'm resolving this as WONTFIX because opDot has been superseded by alias this and is no longer documented and scheduled for deprecation.

When will it be deprecated?
