Hi,
As promised, here's a short patch to add get_offsets() and set_offsets()
to the Collections() base class. I tried to make it do the right thing
with regard to _offsets vs. _uniform_offsets, depending on whether
_uniform_offsets is None. I also had tried to make __init__ use
set_offsets, but that proved to be too much of a hassle for too little
code reuse.
Comments?
