File src/kudu/integration-tests/fuzz-itest.cc:

PS12, Line 574: down_cast<kudu::server::LogicalClock*>(
              :             tablet()->clock().get())
> thats a google style recommendation. we also build the clock inside the tes
Ah, I see -- so it's a code style thing.

The danger of the static_cast<> while doing downcasting: it does not allow to 
see that the operand could not be downcasted to the expected type.  It's 
possible to end-up in a situation when the code executes some other methods, 
not what you expect.  The comment for that down_cast<> method does not make any 
sense to me at all, since I don't understand how one can guarantee that all the 
paths which the code is about to execute are covered with the debug mode runs.  
So, I would either forbid any downcasting at all or allow it and make sure it's 
done with dynamic_cast<> only, so it's safe.
