Mostly for explicitness. I want to be able to say that there is
*explicitly* no seq, not merely that it happens to be a list which right
now is empty but later might not be. Using None for missing values is
idiomatic Python.
You should approve, if only for the sake of consistency: None is meant to
be used as "no such value", and that's exactly how I am using it, even at
the cost of my convenience when writing the code.
