RE: [boost] Pointers to functors with boost::function?

This works with my compiler MSVC6.5 using the just released 1.28 library.  We haven't moved to it yet though.  In the older version library it doesn't work though.

I'm still somewhat interested in whether pointers to functors are useful.  But I suppose it's less important if I can use boost::ref.
