In most languages that have implicit returns (that I’m aware of), the languages are also expression-oriented. For example, in Rust, if/else is actually an expression and you can use the result:

    let result = if foo > 5 {
        "Big foo"
    } else {
        "Small foo"
    };

Implicit returns are just an extension of this (it’s really just “semicolons create statements; if you don’t have a semicolon, that’s the final value of the block”). The explicit return is an actual statement that returns early.

IME the holistic design works pretty well, and I think you can glue together expressions much more naturally this way. The implicit return on itself would be much more annoying IMO.
