yeah this is what I did, too..
However defined as ;
interface I1 {
string opIndex(string columnName);
}
is a no go. So can we say operator overloading within interfaces is not
allowed in D2 ?
thanks again Steve.. try to learn the interface/property stuff.
Jeez, my mistake.. forget to create the implementation. sorry!
LOL! :)
As others have said, templates do not yet work in interfaces, and there is
another subtle problem: templates in interfaces are not virtual so they
cannot enjoy covariance. This is a problem for dcollections which uses
operators in interfaces.
The only solution right now is to reimplement the template in the derived
classes.
Not a fun situation...
