In my opinion this is the way _not_ to learn Rust. These syntaxes are not important at all, and doesn't introduce lifetimes (which is by far the most important part of the language for deciding whether to use it or not).

Any blog about learning Rust for beginners should just contain information that helps the reader decide _whether_ she should put in the time required for learning it, then refer to the great Rust Programming Language book that's really hard to surpass.

The reference is great as well, though personally I miss a part that formally defines the type system in its current form (there are some papers about lifetimes, but they are very hard to read).
