I can show you the code Pretty, with proper whitespace Tell me, coder, now when did You last write readable code? I can open your eyes Make you see your bad indent Force you to respect the style The core devs agreed upon A whole new world A new fantastic code format A de facto standard With some sugar Enforced with clang-format A whole new world A dazzling style we all dreamed of And when we read it through It's crystal clear That now we're in a whole new world of code
