Makes sense. I will try to update the article! Feel free to use whatever library that helps you to compose your program nicely. It would be nice though, if those libraries were in a set of standard libraries ;) If you need to implement all helpers yourself, my point "in Julia, you can just sit down and start implementing a pretty difficult problem" would become a bit watered down... First of all, Julia is also pretty multi-purpose - and secondly, if you put it to the extreme, you could just write a DSL that you parse in C++ that is perfectly tailored to the problem, and consider the challenge as won :P
