Review Comment:
   That's the original code... For this case, IntelliJ complains about an 
unused variable.
   
   Given that we "need" to suppress some warning, I thought it's better to make 
this change, as we don't really create a new `Consumer` and thus the updated 
code is "closer" to what the test does?
