Haskell does not modify existing data; Haskell creates new data when needed and reuses the old ones.

Functional in C++11 and C++14: Dispatch Table and Generic Lambdas

My favourite example the dispatch table shows how nice the features in modern C++ work together. A dispatch table is a table of pointers to functions. In my case, it is a table of handles to polymorphic function wrappers.
