--- Comment #1 from Jacob Lifshay <programmerjake@gmail.com> ---
In my opinion, both == and XNOR (as well as != and XOR) can be used to denote
the same operation, but with two different ways of thinking about it:

1. XNOR/XOR used when flipping bits, (carry-less) adding, LFSRs, etc.
2. ==/!= used when checking for same/different values.

So pick which one you use based on how you are thinking about it, perhaps with
a note about being the same as the other operator when relevant.

Jacob
