Starting with trunk r88411 Nemerle doesn't work anymore.

When I try to compile the following nemerle programm:


public abstract class A[T]
{
    protected a : T
}

public abstract class B[T] : A[T]
{
}

public class C : B[int]
{
    public F() : int
    {
        a
    }

    public static Main(args : array[string]) : int
    {
        0
    }
}


I get an exception:
x.n:18:24:18:28: warning: N168: a function parameter args was never used
x.n:18:24:18:28: hint: replace name with `_' or prefix it like `_bar' to avoid
the warning

Changing
public class C : B[int]
to
public class C : A[int]
solves the problem.

The problem was also reported to nemerle
(http://nemerle.org/bugs/view.php?id=1069) but AFAICS this is a Mono bug.
