`nil` for the case when the error is raised.


        

        
The check is cheap, why not?


      

      
This is kind of misleading, plus this is a dead check. It is __always__
`nil`, or we will get an error in the first test and the second test.
Since we are not testing `pcall()` implementation here, let's just drop
it (it is even cheaper :)).
