I don't see anything fundamentally wrong with using a *sync.Mutex as long
as users always use New(). It allows Set to be passed by value, which is
nice.
But if you keep the mutex as a non pointer, then you probably want to pass
a slice of set pointers:
func (set *Set) Diff(sets []*Set) *Set
This avoids copying the mutex when you create your slice, so the test line
becomes:
set1.Diff([]*Set{set2, set3})
Of course your original Diff code is technically ok. The problem is in
creating a []Set from individual Set objects without violating the mutex
copy rules is difficult, and would require a bunch of code.
