A comparison of C++ concepts and Haskell type classes
Paper in proceedings, 2008
Earlier studies have introduced a list of high-level evaluation criteria to assess how well a language supports generic programming. Since each language that meets all criteria is considered generic, those criteria are not fine-grained enough to differentiate between two languages for generic programming.
We refine these criteria into a taxonomy that captures
differences between type classes in Haskell and concepts in
C++, and discuss which differences are incidental and which
ones are due to other language features. The taxonomy allows for an improved understanding of language support for generic programming, and the comparison is useful for the ongoing discussions among language designers and users of both languages.
