I think this is relevant:
http://www.digitalmars.com/d/2.0/template.html : "Limitations":
Templates cannot be used to add non-static members or virtual
functions to classes.
Templates cannot add functions to interfaces.
But I'm a little confused as to how it all works out. This will work:
import std.stdio;
class Foo
{
void draw(T)(T t) { writeln("Foo"); };
}
class Bar : Foo
{
/* override */ void draw(T)(T t) { writeln("Bar"); };
}
void main()
{
Bar bar = new Bar();
bar.draw(1); // "Bar"
(cast(Foo)bar).draw(1); // "Foo"
}
But uncomment the override and it fails.
Experts will have to chime in on this one. :)
