Ambitious!

I've always been curious about the trade-off between "second-system syndrome" and "learning from experience". Do people have examples of rewrites that went well and those that didn't?

I can think of several that didn't go well (and in fact ultimately decided as tech lead at my last place not to do one for a big chunk of our code that I was on the fence about, just because of that), but can't think of many that did go well.

Maybe Go is kind of an example where the authors used all their experience to build something new, rather than just a straight up rewrite. BurntSushi's ripgrep is an example of someone else doing a rewrite that worked out pretty well. Others?
