[Boost-users] Re: FOREACH with maps

If anyone's interested: I'm playing with the idea of extending FOREACH in a way so that, instead of having a pair<>, you've got two separate variables for key and value. Maybe something like:

map m; ... FOREACH_PAIR(int key, int value, m) { ... }

I'm having a very moderate amount of success. Anyone else playing with this sort of thing?

Can't find the reference now, but someone suggested using tie() from the tuples library for this: int key, int value; BOOST_FOREACH(boost::tie(key, value), m) { ... } HTH, -- Eric Niebler Boost Consulting www.boost-consulting.com
