Note that I'm as guilty as anyone for not understanding or
following these guidelines. I expect we can do much better.
The irony is that D’s private is “public to anyone in this
module”. With that in mind free function or not you don’t get
anything.
Splitting it off to another module is clunky and I’d use it only
for functions that may work for different types (template).
