           Summary: Can't call templated properties as properties from

          Keywords: rejects-valid
          Severity: normal

class Foo {
    int _num;

    int num()()  {
        return _num;
    }

    void doStuff() {
        int i = num;  // Broken
    }
}

void main() {
    auto foo = new Foo;
    auto n = foo.num;  // Works
}


Errors:
test9.d(8): Error: template num() has no value
test9.d(8): Error: cannot implicitly convert expression (num()) of type void to
int

If I comment out Foo.doStuff(), the line `auto n = bar.num;` works, apparently
becuase it's not inside the class.

This seems related, though error manifests outside of class body:

class Bar
{
     property T num(T = int)() const // Note default type
    { 
        T result;
        //...
        return result;
    }
}

void main()
{
    auto bar = new Bar;
    auto n1 = bar.num!int; // Ok
    auto n2 = bar.num; // Error: Bar.num(T = int) has no value
    auto n3 = bar.num!float; // Ok
}

I don't know if it's worth separate issue report.
