There are rare situations when you need to add a certain argument 
to the function signature, but you don't need to use that 
argument inside the method/function. This happens for example 
because of code evolution. In such cases not giving a name to the 
argument is good, you avoid introducing a useless and unused 
variable name, making the code simpler, safer, and more clear.
