   @attilapiros Let's consider a situation when somebody made a changes in 
TimSort, and the test failed. You fixed TimSort, run the test and it does not 
crash, but you want to be sure that results of sorting are correct as well. So, 
you can just re-use the existing code instead of writing it again (or digging 
into history if you know the checking code existed before).
