Review Comment:
Personally I find `String.format` actually harder to read in the "simple"
cases where you're just printing `x=myX, y=myY`. I think where it really shines
is where you want an exotic format (like `x=%02x, y=%08d`, etc.) or where the
textual part is complex. However, I don't feel that strongly about this so you
can leave it.
