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

exception 

        # Exception.exception

(from ruby core)
---
    exc.exception([string])  ->  an_exception or exc

With no argument, or if the argument is the same as the receiver, return
the receiver. Otherwise, create a new exception object of the same class
as the receiver, but with a message equal to `string.to_str`.
