Abstract
C++ Concepts got a lot of bad press and were dropped from C++0x. They were considered too complex with too few benefits. And yet their equivalent in Haskell, type classes, are considered simple and powerful. I will talk about both languages, explaining some Haskell and C++ concept syntax as I go. I’ll give examples of problems that type classes solve and C++ concepts could have solved. I’ll show you the hair-raising forensics of a C++ ADL (Argument-Dependent Lookup) mishap that could have been avoided by using concepts.
