AttributeError: 'arc' object has no attribute 'bbox'

[s1291]

Hello,
I am trying to run the following basic example:

from pyx import canvas, path, deco

rect = path.rect(0, 0, 5, 2)
arc = path.arc(0, 0, 1, 30, 45)
canvas = canvas.canvas()

canvas.stroke(rect, [deco.earrow.small])
canvas.stroke(arc)

canvas.writePDFfile()

When I run it:

python3 example2.py

I get the following error:

C:\Users\PC\AppData\Local\Temp\pyx>python example2.py

path.arc is a path element. Give it as a parameter to path.path to create a path. The third line should read

arc = path.path(path.arc(0, 0, 1, 30, 45))
