Well technically the reverse_range type does solve the problem, the
reverse adaptor doesn't.
But yes I can confirm that your conditional_reverse does prettymuch
exactly what I want.

My mistake, I see that reverse_range is a public type.
However I would suggest that the documentation is less than entirely
clear on this class. As far as I can tell, reverse_range is only
mentioned in the documentation as a return type of the reversed range
adaptor, and there is no other information about it.
Furthermore I think you have shown that reverse_range has utility in its
own right, and hence should be implemented in a separate header from the
reversed range adaptor?
Thanks for your help.
