Hi,
I thought that lambda expressions of the form:
(var(actual_var) = _1)(new_value)
are supposed to work.
Here's a small code that does not compile with boost 1.42 and gcc4.5:
What's the error?  It works for me with msvc 10 and the trunk.
...
#include <map>
#include <boost/lambda/lambda.hpp>
using namespace std;
void foo()
{
    using namespace boost::lambda;
typedef multimap<int, int> MP;
    MP mp1;
    MP mp2;
(var(mp1) = _1)(mp2); //compile-time error here
}
Are standard maps special in that regard?
