reset(). The iterator becomes valid after being advanced with either a pre-increment or an
operator().
For both operator++ and operator(), iterating past the last element will return a value equivalent
to boolean false. Continued increments will return a value equivalent to false until reset() is
called.

struct silly_h{
unsigned long operator()(RWCString x) const

//Duplicate insertion is rejected
