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

to_s 

        # Symbol.to_s

(from ruby core)
---
    sym.id2name   -> string
    sym.to_s      -> string

---

Returns the name or string corresponding to *sym*.

    :fred.id2name   #=> "fred"
    :ginger.to_s    #=> "ginger"

Note that this string is not frozen (unlike the symbol itself). To get a
frozen string, use #name.
