(This is a copy of a [Reddit thread I posted yesterday](https://www.reddit.com/r/nim/comments/73dssr/advent_of_nim/))
* * * I'm a complete beginner in Nim, and I've been trying to learn the basics by solving [Advent of Code](http://adventofcode.com/2016) tasks. I have previous Python experience and [my Python solutions](https://github.com/narimiran/advent_of_code_2016) for AoC were my guidelines for solving these tasks. The things I like in Nim: * speed (most of the time, at least one order of magnitude faster than Python) * "user-friendly" syntax (it was easy to translate some Python parts to Nim) * helpful [tutorial](https://nim-lang.org/docs/tut1.html) * helpful community at IRC channel (if you guys are reading this - thank you for all your answers to my (sometimes quite stupid/basic) questions) * * * [My Nim solutions](https://github.com/narimiran/advent_of_nim_2016) The thing I noticed - in tasks [Day 07](https://github.com/narimiran/advent_of_nim_2016/blob/master/day07.nim) and [Day 09](https://github.com/narimiran/advent_of_nim_2016/blob/master/day09.nim), where I use nre module, the speedup compared to Python is much smaller than usual. Is this the expected behaviour? Or can I do something to improve Nim speed there? But the main reason why I'm posting this (after only 10 tasks) is because I would really like, before I continue with these tasks, if somebody more experienced would take some time to go through my solutions and to correct/improve my Nim. If something can be done more idiomatically, if I should use different data types, if I didn't use some useful module/function, if there's a better and/or faster way to do some things - please let me know. Thank you in advance!
