Yeah, it can be. The more I look at this the more I remember doing it all
for variables, function/method arguments for Randori as well. I mean some

I am still rusty when looking at this and just doing a high level browse
right at the moment.
So is there any other place I am missing in my thought that needs to be
bound, variable and arguments correct?
