Regexes are totally fine in Elixir IMHO. I’ve been using Ruby a lot so I’m totally biased though

Day 2 definitely makes more sense with variable mutation.
I wouldn’t call it cheating, just using right tools for the job.

Yeah, the Raku thing is confusing. There used to be two programming languages.
- One called Perl. The more popular one. This one is still called Perl.
- One called Perl 6. This one changed its name to Raku, as calling it Perl was confusing - it was a completely different language.

My solution is here.
I decided I don’t want to brute-force this, so I made a function which computes the next valid password, on top of which I can build a stream of valid passwords.

Here is my solution : https://github.com/cblavier/advent/tree/master/lib/2019/day4 
I only half brute forced the problem by generating a stream of semi-valid numbers (with only increasing digits) and filtered them afterward

It’s already great you made it through if you’re new to Elixir! 
And it’s a also great and fun way to learn
