Am I doing anything wrong, or range::stride is broken? I think it's a bug of strided_range. Thanks for confirmation, created a ticket: https://svn.boost.org/trac/boost/ticket/5014 I wanted to apologize for this mistake. I can assure you that I am working on this right now. I will submit a fix to boost-trunk today. After a couple of days of passes on boost-trunk I shall merge to boost-release.
Thanks, Neil, great news. Just in case - why stride works for Random Access Sequences only? Why can't I use it for Input sequence like istream_range (e.g. "process every 10th word")? I hope it's already in your Todo list. Also, I don't see any easy way to skip x first elements. "slice" doesn't help as I need to know size that I might not know in advance, for example, in this setup: v | filtered(by) | sliced(5,???) And similar question about skipping n elements at the end of the sequence. Basically, it would be great to have Python-style slice, as it's concise and easy to use, like here:
a=[1,2,3,4,5,6,7,8,9,10] a[3:-3] [4, 5, 6, 7]
Thanks, Maxim
