6914,[Lambda] Add result_of and tr1_result_of specializations for nullary function calls,Michel Morin,No-Maintainer,"To support nullary-callable polymorphic function objects in 
C++03 `result_of`, we have to specialize `result_of` and `tr1_result_of` 
for the zero-argument case. (If we don't provide specializations, 
the type determined by C++03 `result_of` for zero-argument 
function calls is defaulted to void. See the rationale in N1454.)

For example, `phoenix/core/actor.hpp` has such specializations. 
(Note that its current implementation is not perfect: #6911.)",Feature Requests,closed,To Be Determined,lambda,Boost Development Trunk,Problem,fixed,,
