Re: [Boost-users] FOREACH with maps

Thanks very much for all your replies. I wrote

However, for maps, the second variation (declaring outside the macro) doesn't work:

map m; ... FOREACH (map::value_type i, m) {...} // compiles map::value_type i; FOREACH (i, m) {...} // COMPILE ERROR

And the various replies are right on the money, and appreciated. I thought it was something like this, but I couldn't quite figure out what was going on. 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?
