Agreed.  There's three big reasons why it isn't so right now:
1) NumPy didn't exist when the first PIL versions were written,
2) it's quite important that PIL can be used on its own, and 3)
a lot of PIL-related code depends on the current Imaging
structure layout.

Moving the multiarray stuff into the Python code would help
a lot...

PIL 1.1 will most likely support "access adaptors" which would
make it possible to treat NumPy arrays (and various other things)
as image memories.  (It's too early to ask "when"...)
