encapsulation issue with Couchbase::Model ?

[infiton]

when a couchbase model has a mutable attribute you cannot modify that attribute in place without changing it for all other instances of that class:

class Foo < Couchbase::Model
 attribute :foo, default: []
end

f = Foo.new
f.foo # => []
f.foo << "Hi"
f.foo #=> ["Hi"]

g = Foo.new
g.foo # => ["Hi"]
g.foo << "Bye"

f.foo # => ["Hi", "Bye"]

apologies, this is a duplicate issue: #6
