Comment(by SimonKing):
I just noticed that the second patch also changes old names: The old
attribute `blocks` is renamed `__blocks` in the second patch, and there is
a new method `blocks`. Hence, what used to be an attribute became a
method.
Even worse: An old pickle may contain the old attribute `block`. When
reading it, wouldn't that attribute `block` override the new method
`block` (unless one has an appropriate `__setattr__`, of course)?
That said, I do think that `block` should better be the name of a method
and not of a plain attribute.
And again, the question (addressed to all of you) is whether the reason
for these changes is sufficient. There ''is'' a reason, but the changes
make backward compatibility needlessly complicated IMHO.
