This is a Ruby tree! It shows every object from the Ruby Programming Language in a tree format.

<=> 

        # File::Stat.<=>

(from ruby core)
### Implementation from Stat
---
    stat <=> other_stat    -> -1, 0, 1, nil

---

Compares File::Stat objects by comparing their respective modification
times.

`nil` is returned if `other_stat` is not a File::Stat object

    f1 = File.new("f1", "w")
    sleep 1
    f2 = File.new("f2", "w")
    f1.stat <=> f2.stat   #=> -1
