Given a bidirectional range R, is it possible to select at compile time whether we want to iterate forwards or backwards?

Below is a test app. At the commented line, I would like to transparently construct a forward or reverse range, ie either [begin(range), end(range)] or [rbegin(range), rend(range)] respectively, depending on the definition of the Reversed template parameter.

Just to be clear, the desired output is:

forward: abc
reversed: abc

I can make this work by using a functor class with partial specialisation to construct the iterator_range, using begin/end or rbegin/rend respectively. But it's a bit ugly and it would seem like something that boost range would provide anyway?

(Note that boost::reverse() is NOT what I am after.)
