Tuples can be difficult if they're not explained properly, and
I don't find a lot of good material around that really brings
out the salient points.

For me at least, the basic thing about tuples is that they're a
quick way of bundling a bunch of objects together when you
don't want to go to the trouble of creating a special purpose
object to hold them.

I think that the use of implicit tuple creation on the return statement
and sequence unpacking make this point quite well.

I find that classifying them as sequences is essentially confusing,
and also stating that they're immutable is, while true, also confusing.
