You can use make_function with a Signature parameter and pass that to
add_property.  But your bind expression above won't work.

Maybe something like:

 	.add_property("aaa", 
        make_function(
            boost::bind(&Foo::lookup, _1, "aaa")
          , default_call_policies()
          , mpl::vector1<int>()
        )
     )
