I agree, we should document it, unfortunately our documentation is still
woefully inadequate :(. Maybe someone could add it to the IronPython cookbook
page in the mean time? (http://www.ironpython.info/index.php/Main_Page).
But as for it "working in C#"... Consider the code:
using System;
public class Foo : ICloneable {
public object Bar() {
return Clone();
}
object ICloneable.Clone() {
return null;
}
}
That code doesn't compile because you must be explicit to access the Icloneable
method. This compiles:
using System;
public class Foo : ICloneable {
public object Bar() {
return ((ICloneable)this).Clone();
}
object ICloneable.Clone() {
return null;
}
}
As does:
using System;
public class Foo : ICloneable {
public object Bar() {
ICloneable x = this;
return x.Clone();
}
object ICloneable.Clone() {
return null;
}
}
But you must explicitly refer to the type somewhere. Unfortunately we don't
have type information at compile time so the only way to refer to the type is
at runtime by getting the method from the interface. But in either case both
languages are requiring you to be explicit about your choice of method. So
conceptually I think we're fairly similar.

Thanks for the explanation. The docs could/should mention that... :) I guess
we're not used, because it works in C#, so it should double-work in Ipy. You
know, inferred types and all... :))
rgds,

It's a feature, explicit interfaces require an explicit call :) .
