Naming a parameter "e" for a Task in an IGrain interface causes code gen to fail

[jschieck]

Example:

public interface IGlobalEventManager : IGrain
{
        Task AddNewGlobalEvent(IGlobalEvent e);
}

It will generate into something like this, which does not compile

return base.InvokeMethodAsync<object>(-749076116, new object[] {@e is global::Orleans.Grain ? GrainInterfaces.GlobalEventFactory.Cast(@e.AsReference()) : @e} );
