[iterator] readable and writable transform_iterator
I can't figure out how to make a writable transform_iterator work.
Here is what I have:

transform_iterator doesn't make use of boost::result_of, IIRC. You have to define a nested `result_type` in `Get`, or you can use transform_iterator<..., a_result_type>. Regards, -- Shunsuke Sogame
When I looked through the code in SVN, it appears you are right.
Unfortunately, the docs say it uses result_of.
Thanks,
Chris

Chris, Could you file a bug report about this at http://svn.boost.org ("New Ticket") so I don't forget to address it? Thanks, -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
It put me in as anonymous, but the ticket is here:

The cure for that is to sign in to Trac. See the instructions at http://svn.boost.org for creating tickets. -- Dave Abrahams Boost Consulting http://www.boost-consulting.com

Without getting too far into your code, you need to make sure that the function (object) you use returns a reference, not a value. -- Dave Abrahams Boost Consulting http://www.boost-consulting.com
