Comment:

 The above code still prints "0 4 8 12 16 20 24"
 instead of "0 4 8 12 16 20 24 28".
 This is because, when constructing {{{strided_range}}},
 the end iterator of an input range should advance forward rather than
 backward.
 The regression test (libs/range/test/adaptor_test/strided.cpp) passes
 because a similar thing happens when populating {{{reference}}} in
 {{{strided_test_impl}}}.

 Please see:

 (The codes in the mail assumes stride is greater than zero...)
