Completely agree: tabs FTW. I wish I could find the reference, but when dealing with mono-spaced fonts, readability is apparently enhanced with THREE spaces per indent. Now, good computer people hate non powers-of-two, so it's either 1, 2, 4, or 8 spaces!!!! I guess I'm not a good computer person, because my eyes find tab stops at '3 spaces per tab' just right.

TIL some people use 3 instead of a power of two. I would never had thought of it nor would I have considered it as a reasonable choice. And now I wonder why I would have thought that.

I also use 3 spaces myself, because 4 spaces is too damn wide and 2 spaces is a little bit too small. I would use tabs instead, but rustfmt doesn't handle it well at all in some of the nightly options, I've had it use spaces where it should use tabs a lot.

I remember suggesting it as a jokey promise over a decade ago, but got curious and tried it myself. It also seems just right to me, and is what I've used in all my personal projects ever since.

I have used tabs with a three-space width since forever, and it is indeed the better spacing.
