boost 1.32 breaks my code 2
Ok I have an example, int f(int, int); struct X { int m_i; }; X x; int i = boost::bind(&f, 1, _1)(boost::bind(&KTstbX::m_i, _1)(x)); UNREF(i); I guess the new boost does not return ref for members (in react on a previous email). Be aware however that functions them selves can still return references.

Yes, you are right.
I don't quite see the point of the example, though... the inner bind is not
a nested bind expression. Is this an oversimplified version?
The problem is that bind( f, 1, _1 ) can't take an rvalue as a parameter.
This hasn't changed. It's just that the second bind now returns the member
by value by default.
If you are using a reasonably conforming compiler, you can use
bind
Yes you are right, it was a simplification.
We have a STL extension library here (which by the way is a good idea for
boost), which applies <algortihms> to complete containers, like:
template
