Dear all, Another small issue have surfaced regarding operator==(), operator!=() and operator<() (the latter currently not there). The current behavior is compare the two underlying iterators. I would suggest to change this to compare the objects in the underlying range. The motivation would be the follwoing: 1. comparing the iterators is seldom useful and can be done explicitlty or by a new member function equal() 2. comparing the objects is the range is highly useful and allows for code like sub_range<string> sub = ...; if( sub == "foo" ) 3. operator<() cannot be defined for iterators in general and hence we couldn't put iterator_range into a set/map; Any comments? An additional question would be if operator> operator>= etc really needs to be defined? I would support just to have ==, !=, < to start with. br Thorsten
