No good reason, really :-) -- just a gut feeling/bias that when problems move from "tricky" to "easy", people end up creating new/unexpected tooling as a result

No good reason, really :-) -- just a gut feeling/bias that when problems move from "tricky" to "easy", people end up creating new/unexpected tooling as a result, just because it's easier. Might well be totally irrelevant here. Sadly I don't know Rust (yet!), but Cargo certainly seems widely loved and admired. Perusing the resolver code was pleasant, and impressive. We've come a long way from when you'd pull back the covers on a C++ std library or (god help you) boost, and run away screaming in terror. The future is bright!
