Chris:  In the pylab interface, figure() returns a figure instance and 
plot(x,y) returns a list of Line2d instances.

 >>> from pylab import *
 >>> l = plot([1,2,3])
 >>> l
[<matplotlib.lines.Line2D instance at 0x3dcf738>]
 >>> f = figure()
 >>> f
<matplotlib.figure.Figure instance at 0x3dcf710>
 >>>

I guess I agree with Eric, I don't really see much benefit for the OO 
interface for interactive use.
