               # Note about TestRequest#problem: Usually, A TestRequest has to be
               #   associated with a problem, so that execution environment can be
               #   determined.  However, to be more flexible, we have to ensure that
               #   it works as well with problem=nil.  In this case, we shall provide
               #   a "default" execution environment for it.  This can be done
               #   seamlessly by using TestRequest#problem_name or
               #   TestRequest#name_of(problem) when retrieving the name of the
               #   problem: #name_of would return problem.name when problem!=nil and
