    If you think Python is like that, I advise you to 
    never look at Ruby codebase.

The codebase for Ruby itself, or the codebase of your typical Ruby app or library?

I spent about a decade with Ruby and my general impression is that the community really moved away from overly-clever metaprogramming.

The codebase for the Ruby language itself is definitely a challenging read.
