Are you sure you're actually calling the function_adaptor object? The
result member is necessary as soon as boost::result_of is
instantiated, which happens when you invoke the function_adaptor's
call operator.

Also, you may be interested in an upcoming new feature. When Boost
1.44 is released you will no longer need to define result if your
compiler supports C++0x decltype. To enable this new feature define
BOOST_RESULT_OF_USE_DECLTYPE before including
boost/utility/result_of.hpp.
