Note that I'm as guilty as anyone for not understanding or
following these guidelines. I expect we can do much better.
As a counterpoint. I guess UFCS makes it less of a problem, but
it's nice when using an IDE to just type foo. , press ctrl-space
and see a nice list of methods that can be used with the class.
When having free functions, you don't get to enjoy that :)
