That's because of currying. If you want to partially apply parameters, in your example, with Haskell we would just have to do this:

        someLongAssFunctionName someQuirkyParameter

And we get a function that accepts one parameter. But in Rust you would have to do this:

        move |another_one: i32| {
            some_long_ass_function_name(some_quirky_parameter, another_one)
        }

Which is not easier to read.
