Dealing with complex C-structure-like data in haskell often force the developer to have to deal with C files, and create a system that is usually a tradeoff between efficiency, modularity and safety.

The Foreign class doesn't quite cut it, external program needs C files, binary parsers (binary, cereal) are not efficient or modular.

Let's see if we can do better using the advanced haskell type system.

A new hope. Foundation is a new library that tries to define a new modern Haskell framework. It is also trying to be more than a library: A common place for the community to improve things and define new things

Rust is a pretty interesting language, in the area of C++ but more modern / better. The stated goal of rust are: "a systems programming language focused on three goals: safety, speed, and concurrency". Combining Rust with Haskell could create some interesting use cases, and could replace use of C in some projects while providing a more high level and safer approach where Haskell cannot be used.
