[229] Invalid error on generic interface/generic type

Though there are some problems in ReSharper (which will be fixed shortly),
you code is not compilable - method cannot have the type parameter named as
the type parameter of the interface

Hello, this following (bad) example compiles (with warnings), but is
indicated as an error in R#:

>

public interface ICloneableGeneric<T> : ICloneable
{
T Clone<T>();
}

>

public class CloneableList<T> : List<T>, ICloneableGeneric<T> where T
: ICloneableGeneric<T>, IDisposable
{

>

T ICloneableGeneric<T>.Clone<T>()
{
throw new Exception("The method or operation is not
implemented.");
}

>
>

object ICloneable.Clone()
{
throw new Exception("The method or operation is not
implemented.");
}
}

I know it's trash code, it's just that Visual Studio compiles it with
warnings (it probably shouldn't), but R# gives the wrong error message
('interface not implemented')...

Thanks!

This code is not compilable!

Type parameters cannot have duplicate names
