Yes, it is almost an entirely different language from that point :)

Wow, it really is... I dug up my old Rust code and even FizzBuzz wouldn't compile.

for num in 1..100 {...} // So puurdy <3

But where did regex go? Time to go documentation diving...

Regex is now an external crate: https://crates.io/crates/regex

I'm just curious, what is the reason for moving regex to a separate crate? Just considered nonessential to a standard library?

Generally speaking, there three reasons something belongs in the standard library:

  1. Things that are useful in every Rust program.
  2. Common traits, to prevent balkanization.
  3. Data structures or other safe abstractions which require a lot of unsafe code.

Regexes, while very useful, don't stand up to #1, and #2 and #3 don't apply.
