I don't know much about rust, but I am just curious why the last line doesn't have a "return" keyword? Does it just assume the last line is the value to return? Could you include the "return" keyword if you wanted?
If there is no `;` then the last statement is considered the return value. You can include the return if you want but then you also need the `;` at the end.
… which it is, if you know ahead of time how the language is structured.
If you mean ‘not intuitive for someone who never wrote a single line of rust before’ then fine. So is literally any programming language concept. FP is not intuitive for someone who only ever done OOP/procedural programming, and vice versa. Rust is structured differently from most other languages, therefore intuition doesn’t necessarily transfer over. Let’s not be pedantic.
But if you coded in rust for more than 10 minutes you’ll realise everything is an expression, which then makes aspects of the language, such as implicit return types, intuitive.
