a,b, not much to sayThe hardest part has finding the right dart ascii library to use (by default dart treats everything as UTF-16, which is horrible for this sort of thing) and the right data structure (linked hash map, which is a map that remembers insertion order.)

"you have linked hash maps? LUXURY!"

In my code I had to resort to this sorting

for my $lens ( sort { $Boxes->[$idx]{$a}{pos} <=> $Boxes->[$idx]{$b}{pos} }  keys %{ $Boxes->[$idx] } )

Perl at its best!

It's a nice language! And I believe it's what AoC is made in. Certainly a lot of stuff seems tailor-made for the language.
