Thanks.  I understand what _1 does.  I thought that leaving off the real arguments and 
giving only the object would produce a function object taking those same arguments.  I 
guess the compiler can't hand that automatically?

Now I get

when followed by '::'
         V:\boost_1_47\boost/bind/bind_template.hpp(15) : see reference to class template

F in the first complaint is the pointer-to-function type, so I agree that F::result_type 
doesn't make sense.
