C'mon, this is a bs "research".
Fore example, is this Java (65.72% dryness)
if (condition){
Blah();
}
really more dense than this C# (58.4% dryness)?
if (condition)
{
Blah();
}
Now, does this Clojure 77.91 dryness) really beats them both to that margin?
(if (condition)
(blah)))
This metric measures formatting more than anything else. I don't even go to other more nuanced details.
