The design of the examples is weird and unintuitive. At the very least should have some sort of clarifying header of “new” and “old” or something. It took me a solid 30 seconds of confusion to realize the regex was the old syntax rather than the new syntax. The arrow points from left to right, and arrows represent progress but that’s backward from their intent. The new syntax should be on the end of the arrow, not the beginning. If this were a regex transcoder and the base were the input syntax and the tip were the output code it could kinda make sense, but best I can tell that is not the case here. The examples read backwards.
