I looked at this article briefly, and perhaps I have been using 'mutator' incorrectly at times, in previous posts. That is to say, I had certain CVs of mine where I simply proposed to swap only [one or] two pieces in the setup for another kind of piece (e.g. frogs for FADs in the setup of a CV I had already published), and I wrote it was a mutator. Without looking carefully, or checking for more recent usages/updates of the term 'mutator', on CVP site, I don't know for sure if my usage of the term was incorrect.
