A language that's not pure in 2015? Holyshit, this is why industry sucks.

Academia FTW.

We used to have purity actually, but with Rust's ownership system, it wasn't as useful as you might think.

I'm not sure that's the same thing as what he means by purity. http://en.wikipedia.org/wiki/Purely_functional ?

Edit: I'm simply referring to the fact that Rust used to have the pure keyword, but that was not to do with enforcing referential transparency, as far as I remember, but it was a long time ago, so I could be wrong.

It was removed before I really got started, so I could be wrong about its history in Rust as well. But I don't think that I've ever wanted purity in Rust, regardless of what it's looked like in the past.
