@acraileanu Although your statement is true, it is still considered a good practice not only to prevent problems associated with pass-by-reference but also to avoid confusion that arises from having parameters with names that suggest permanence (as is the case with this Kata) but with values that change throughout their lifetime.

Imagine, too, the frustration experienced by a maintenance developer who, wishing to reuse the original value of a parameter, comes to discover that, where he has inserted his own code, the original value no longer exists.

Ultimately, there is just no need to reassign parameter values and hence the existence of the formal refactoring "Remove Assignments to Parameters."
