You make it sound like it's a burden, but "dealing" with two objects is not
something extraordinary or bizarre, it happens all the time when you do network
programming: e.g. ('', 80).

(or would you argue that Address objects should have an optional distinguishing
port number, for "convenience" reasons?)

If you need the two objects, whether you access them through separate variables
(`network` and `host`) or through attribute access (`network` and
`network.host`) doesn't really matter. You can even pretend the tuple is an
atomic object and store it as-is if you want. I'm not sure what annoys you here.

I don't see how it's similar, since a float is a clearly defined atomic entity.
Most float operations become meaningless if you consider the integral and the
fractional part separately.
