Is there a reason why there is no "review" link? Could it be because the file
is uploaded as is rather than as a patch?
In any case, I have a question about this code in sum:
# Convert running total to a float. See comment below for
# why we do it this way.
total = type(total).__float__(total)
The "comment below" says:
# Don't call float() directly, as that converts strings and we
# don't want that. Also, like all dunder methods, we should call
# __float__ on the class, not the instance.
x = type(x).__float__(x)
but this reason does not apply to total that cannot be a string unless you add
instances of a really weird class in which case all bets are off and the dunder
method won't help much.
