Thanx for the reply.
If by dereferencing the pointer you mean
for_each(shapes.begin(), shapes.end(), bind(&shape::draw, *_1, 2));
then I get another error - cannot instantiate abstract class.
Plus I would expect the dereferencing to slice off the derived bits of
circle and rectangle.

The last statement fails under VC++ 2008 with error C2665: 'boost::lambda::function_adaptor<Func>::apply' : none of the 2 overloads could convert all the argument types
Dereferencing the pointer should work with the current trunk.
