    Rust would allow you to

    let ret = if some_condition {
    <a lot of expensive calculations>
    result_of_operations
} else {
    <a lot of other different expensive calculations>
    result_of_other_operations
};

    Now you don’t have to declare it inside the blocks.

        What’s disgusting about it? The only thing I can think of is the implicit return, which felt a bit icky at first.

        Also, as the if expression is an expression, you can call methods on it like so:

        if 1 > 2 {
    3
} else {
    4
}.min(5)

        (the above is still an expression, so it could be used, for example, as part of a condition for another if)

        Of course, you can write horrible code in any language, but the ability to use blocks where expressions are expected can be great sometimes.
