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.

I think using calling the variable 'dummy' would likely do the
trick in those instances, but this makes sense.
