Contribution to dyn::



C++ provides a good support for performance and genericity through templates. However, it has a real cost on flexibility and compilation time. In order to overcome these issues, Vcsn introduces a dynamically-typed library named dyn. The purpose is to bring more flexibility to the project and it also allows just-in-time compilation. This work presents, first of all, our thoughts on how to handle and optimize our compile time, then various improvements added to dyn.
