Effective Go has always said:

Do not communicate by sharing memory; instead, share memory by communicating.

This approach can be taken too far. Reference counts may be best done by putting a mutex around an integer variable, for instance.

I'm not sure making an absolute statement ("do not...") followed by "... actually do, sometimes" is helpful. How is this different to any other language that gives you a toolbox of synchronisation primitives?
