"How Non-Member Functions Improve Encapsulation" by Scott Meyers

Note that I'm as guilty as anyone for not understanding or
following these guidelines. I expect we can do much better.
I tend to agree. When a member function can be written with only
the public declarations (aka the "public API") it can be set as a
free function. However during my youth i've written lots of huge
classes...now that i don't write much anymore it's too late to
apply the rule :/
