add operator like typeof for get symbol as string, i.e.
class ViewModel : INotifyPropertyChanged
{
private string _name;
public string Name
{
get { return _name; }
set {
_name = value;
//RaisePropertyChanged("Name"); // old way
RaisePropertyChanged(symbolof(Name)); // and strongly
// way, with full sypport refactorings and fast as
// default string contrant, compile time inlining..
}
}

many lib requires string representation of property name or method name, and this operator can improve quality
