Edit:

To clarify, I looked at existing online ruby code and gave it a small test for readability. It may be outdated, use uncommon syntax, bad practice or be full of individual developer quirks - I wouldn't know. I did that because I wanted to highlight some weaknesses of the language design that turned me away from ruby years ago. https://en.wikipedia.org/wiki/Principle_of_least_astonishment

Yes, very nice. But here comes the ugly;

[1,2,3].map(&:to_s)

oh ok, a bit hieroglyphic, but I can figure it out, seems like '&' means element and ':' means what I do with it.

files = `ls -1`

Aaah so a backtick is for strings? WRONG!!! IT EXECUTES THE FUCKING COMMAND!!!

ARGF.each { |line| puts line if /BEGIN/ .. /END/ }

What the hell is | and / ? Oh but I guess .. is a range like in other languages, but what would be that range??? WRONG! I!!T'S A FLIP FLOP!!!

%w{a b c}     # array of strings
%i[foo bar]   # array of symbols
%r{https?://\w+}  # regex
%x(ls -1)     # run shell command

Ah, just memorize which letter to use by heart and that % is for type and that [ = { sometimes. But { unequal to { other times.

if line =~ /ERROR/
  warn $~.post_match
end

=~ neat!

$~ dafuq???

At this point I feel like ruby devs are just trolling us. There are always multiple ways to do the same thing. Every example from above also has a tidy and readable way to do it. But the alternative ways become progressively more shorthand, unreadable and unintuitive.
