The thing I hate about rust is abbreviated keywords like “fn” and “mut” because it sounds like fricken mutt. A function is a function not a fn, and is it really so hard to type “mutable”?
There’s more important things in life to worry about than rewriting codebases in language Z.
Edit: Fat arrow?
I don't read code in English, even though I'm a native speaker. So its kindof a silly question: this would only come up when walking someone else through the code. I internally read code using data-flow and control-flow graphs. The written abbreviation is just shorthand for a specific type of graph vertex (or edge).

There is Func<T> - that's a delegate type.
