Fighting spam with Haskell
I am under the impression that a large part of engineering effort at established companies go into porting existing components to a deemed to be more appropriate language for that task.Is it plain impossible to pick the best fit language without implementing a solution in the first place and fleshing out the requirements and challenges that specific to the problem space? Or do the problems evolve fast enough that no matter how well you design the system, it will need to be deprecated once in a few years?
