next guess at a better name for setdefault would be:
value = container.GetOrAddDefault(key=a, default=[])
value.append(listvalue)
but that's kind of confusing too, but it better describes what is happening.

I haven't tried this myself, but I think the secret to displaying a
continuously updating %done on the command line is to
print file 100, 1% done
then send exactly 7 backspaces to the terminal, then print 2% done...
so the backspaces will write over the previous text.

Oh, I see. Yeah, having the code look like you're instantiating one
class, but really getting a different one is really horrible. Sorry I
didn't catch on to the subtlety. I'm always complaining about code

I did a test with wxPython 2.6.1 on Windows. I created a G4 TIFF
image that was 4400 x 3599 big, and the following code took under a
half second.
import wx
import time
def readImage(filename):
img = wx.Image(filename)
w = img.GetWidth()
h = img.GetHeight()
value = img.GetGreen(w
Returning instances of some other class is not so horrible. They're
called FactoryMethods usually.
An example is when you have a polymorphic tree of image file reader
objects, and you open an image file, it might return a JpegReader
