This implementation is invalid. First of all, it's not a valid Jule code. Have undefined semantics and invalid syntaxes. For example, module reverse_string is invalid. Jule have not such a semantics.

Also Jule variables are immutable-by-default but you are mutating the s parameter which is immutable. Also strings are not mutable, so you should cast into byte slice first. But reversing byte slice is not a correct approach. So you should cast string into rune slice, reverse rune slice, and return as string the rune slice.

There are too many issues. Such as pub fn or return keywords. Jule have ret keyword for return statements. Have no pub keyword and etc. Please write your code syntactically and semantically correct, and test it whether it compiles successfully.

Your tests are invalid. Please write valid test functions.
You can look at the existing tests of existing implementations for reference.
