alt Hacker NewsI think a lot of people taking this at face value , a lot of this was possible because of the beyond standard extensive and comprehensive test suit previously built.

If this is a "beyond standard" test suite, (so much so that it _uniquely_ makes this work possible compared to other projects,) then how is Bun also uniquely unstable compared to other Zig programs (and so deserving of rewrite?) If the blame lies partially with the test suite, what does this imply (if anything) about the Rust port?

Look what it can do in 6 days!
Ignore the hundreds of thousands of hours put into the original architecture and test suite that made it possible in the first place.

It's still an impressive achievement that would have taken even the most competent engineers an exponentially longer time to accomplish.
I just hope it's noted when this is eventually marketed how much human effort went into designing and curating the test suite that even enabled this speed in the first place.
A test suite sort of functions exactly like the ideal scenario for current gen llms. A comprehensive enough test suite essentially forms the spec for agents to implement however they see fit - in this case rust.
You could probably throw away the entire actual source code in certain cases and reimplement the whole thing from scratch just giving an agent access to the tests when it's as well crafted as a project like bun.
