Comment:

 I'm marking this as a duplicate of 7630 now since that seems to be the
 more general issue. I've been worrying about this lifetime issue for
 sometime, but haven't a good solution. I spent a little time looking at
 the BOOST_FOREACH implementations and I'll take a look at some of the
 suggestions made for ticket 7630. It might be that this can now be made to
 work well with the C++11 support becoming much more mature and the rvalue
 support that much more reliable.

 I hope I don't cause any offence by collapsing this into one defect.
 Please feel free to make comments on the #7630 ticket.

 Since there is even an example solution I should be able to find a way to
 make this work. I'll obviously have to take care to ensure that the fix
 doesn't introduce any unexpected nasty surprises.

 Thanks for helping.
