One really annoying thing about PIL is that it's importable as Image and PIL. It leads me and other newbies to think if it's different. I don't want choices:
Python 2.6.2 (release26-maint, Apr 19 2009, 01:56:41)
[GCC 4.3.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import PIL
>>> import Image
>>> ?
When PIL/Image is put into standard lib, can we call the module: imaging?

True
"There should be one-- and preferably only one --obvious way to do it"
Whatever it is, it better be consistent.
