Actually, no, I've never used C# except for a few minutes and only one time. I have more experience with the syntax of Scala and Rust. Between the two, I found Rust's more appealing. I like that enums serve a single purpose and can't be inherited.

Currently, the best you can get for iteration of Lists and Hashes is to do each-ing the way you'd go about it in Ruby, except that the language currently lacks iterators.

That's not to say I don't want iterators. But I've spent a huge amount of time of this release in making sure that all of the built-in classes get dynaloaded so that memory usage stays low. Now that everything's getting dynaloaded properly, I've less of a problem with doing iterators.
