Curled hair is 'J' only.

Unless i'm missing something I think it's there:

trim any curled hair --> replace 'J' with '|'
trim any hair from the chin (last array) --> replace '|' or 'J' with '...'

Oh, didn't expect to encounter here another gaijin knowing the HnK franchise: quite a surprise :o!

Well, then I can also compare myself to the usually lame Jagi in Gokuaku no Hana: he felt always weak and not progressing while still training with his bigger brothers, then, suddenly, he realized how much his skills developed once he had to challenge ordinary guys; I experienced a similar thing trying some task out there and found that all sparring with bigger brothers bore good fruits, but I didn't realize until then.

Be my guest, then: CW gave me a lot, in more than a way.

So I am more than ready to give something back to the community, as much as my meager skills allow.

Plus, discussing with a fellow coder is always a chance of growth :)

On a side note, when I started CW I only had a very little proficiency with Python and very few concepts of other languages grasped on CodeCademy, having to Google basically everything in both Ruby and JS. Well, hanging around here apparently worked wonders on me.

Oh, that's pretty easy, Dario: I wouldn't even dream of putting something like this without even a comment into something which is not just for fun.

For a production environment, I would first of all try to find a common ground on the field of conventions (naming, spacing, etc), then I would tune myself with the rest of the staff and try to stay on that track.

I assume you didn't see all of my Python solutions for this series of kata, otherwise you wouldn't bother considering this poorly readable ;)

But then again, as I often like to say, to me it is like jogging with extra weights: practice to grow some muscles (my abstraction skills in this case) so to perform better in the long run :)

Thanks for your kind attention and your time considering my solution, feel free to ask whatever else you may find that I can answer or provide :)

Cheers. And in Ruby you also use @@ when declaring class variables!
