 -- | Lower level assertion function that works for a wider array of test
 -- frameworks.
+--
+-- This function can make two different assertions. It fails if the values fail
+-- to parse, and it asserts that the values are equal to the expected value.
+-- This latter assertion is only done for the most recent version because
+-- changes that impact the structure of a data type can result in erroneous
+-- failures due to changes in the order that the test cases are generated.
+--
+-- In other words, if you make an innocuous change like adding a constructor and
+-- start getting "values didn't match" failures, all you need to do is bump the
+-- data type's version. Armor will still guarantee that those serializations
+-- parse properly but the incorrect value failures will be suppressed.
