This is a very, very misinformed comment. I want to address it,
especially the statement "It's certainly a code bloat." It is
absolutely *NOT* code bloat to define a sum method for
I agree, John. It would be better to define a .sum() method on the
generic vector class, which calls the global sum(). Then, it'll be
overridden by various classes which can do it faster.

I'm not sure I agree with this. I would expect the global sum() to
try to use a sum method first, and only do the default if that did not
exist, since some classes might have better ways of summing themselves
than the default. But then the only reason for having sum methods
would be if there was
