Is ⇇ different from ⇐?

(Whole-object, field-by-field mutation vs. mutation).

I try to show my thinking as it’s happening, which means that I might show/write things that are unfinished thoughts that may need re-thinking. Readers should remember that I reserve the right to be wrong.

When I was manually preening the code, my “gut” said that I needed two kinds of mutation operators. After I wrote this note, I’m no longer sure as to why I was so adamant about this. Often one’s “gut feel” is correct and, usually, one should go with it, which is what I did in this note. I might remove ⇇ in a few days, after more thought. Comments welcome.
