+ * In order to make assertions easier, this function strips `symbol`'s from
+ * the incoming data.
+ *
+ * This can be handy when running tests against `apollo-client` for example,
+ * since it adds `symbol`'s to the data in the store. Jest's `toEqual`
+ * function now covers `symbol`'s (https://github.com/facebook/jest/pull/3437),
+ * which means all test data used in a `toEqual` comparison would also have to
+ * include `symbol`'s, to pass. By stripping `symbol`'s from the cache data
+ * we can compare against more simplified test data.
