  Randomized testing for Go

It does instrumented fuzzing. The older https://github.com/dvyukov/go-fuzz would rewrite your sources to inject the instrumentation and pass the rewritten sources to the compiler, but it didn't really work with Go modules. This is something that probably makes sense to integrate with the compiler toolchain, same as `go test`'s coverage testing.

I agree - I took a look at the minimization algorithm[0] and it seems like it loops through a few basic options, with the last one basically normalizing all possible bytes to something readable (like "0"). Part of the issue with trying to be as generic as possible is you sometimes can't find the best solution to every problem, this might be one of those situations.

I know the goal of 1.18 was to get the UX down, so I'm interested to see how it improves for 1.19.
