Indirect Functoids This is perhaps the most Boost-redundant feature of the library. FC++ indirect functoids do almost the same thing as boost::function objects. The differences: - indirect functoids are imbued with "full functoid" features - indirect functoids don't work with non-const reference parameters, whereas boost::function object do - indirect functoids can't be "null", whereas boost::function objects can There is also an implementation dependency that FC++ lazy lists rely on indirect functoids in their implementation, but I think this dependency could be removed (creating a dependency on boost::function instead). If FC++ were accepted into Boost, my gut tells me that in the long-term, indirect functoids would naturally disappear (by getting absorbed by boost::function). -- -Brian McNamara (lorgon@cc.gatech.edu)
