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

print 

        # IO.print

(from ruby core)
---
    ios.print               -> nil
    ios.print(obj, ...)     -> nil

---

Writes the given object(s) to *ios*. Returns `nil`.

The stream must be opened for writing. Each given object that isn't a
string will be converted by calling its `to_s` method. When called
without arguments, prints the contents of `$_`.

If the output field separator (`$,`) is not `nil`, it is inserted
between objects. If the output record separator (`$\`) is not `nil`, it
is appended to the output.

    $stdout.print("This is ", 100, " percent.\n")

*produces:*

    This is 100 percent.
