(To help reviewers digest the FC++ library in smaller chunks, I am starting individual threads on each of the main chunks of the FC++ library.) Direct Functoids Direct functoids are the FC++ representation for template functions. The look like normal function objects, but with an added "sig" entity which is used for return-type deduction. A number of different C++ libraries all discovered the same general trick for computing return types. Recently, "result_of" has been accepted as the standard way to ask for a function's return type given certain argument types. FC++ full functoids are compatible with result_of. When an implementation of result_of appears in Boost, FC++ could switch to using this representation natively (rather than using its own "sig" structures). This may also help FC++ interoperate more easily with other libraries which rely on return-type deduction. Overall, there is not too much to say about this "chunk" of the library. -- -Brian McNamara (lorgon@cc.gatech.edu)
