Rémi Verschelde 5dbf1809c6 A Whole New World (clang-format edition) 
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
