Having the following code (where 'out' is a std::ostream):

out<< boost::tuples::set_open('[') << boost::tuples::set_close(']') << boost::tuples::set_delimiter(',') << std::setw(21)<< std::right<< get_some_tuple();

I expected to see the tuple in a column of 21 spaces, adjusted to the right. Instead, the tuple is appended on 21 spaces. Any hint on what my mistake is?

You didn't make a mistake. This is a very common error in implementing stream operators. Please file a ticket at http://svn.boost.org/, and I'll fix it as soon as I can. In Christ, Steven Watanabe
