?:演算子を 右結合に operator ?: changed to right-associative.

使いやすくするため ?:演算子を 右結合に変更を提案します。

I request that operator ?: can be changed to right-associative for easy of use.

function test() {
    println( compare10(10)); // ==> "same"
    println( compare10(5));  // ==>  error
}

function compare10(a) {
    return (a<10) ? "small" : (a==10) ? "same" : "big";
}

// left-associative    ((a<10) ? "small" : (a==10))? "same" : "big"
// right-associative    (a<10) ? "small" (a==10) ? "same" : "big")

Thanks for pointing this out.  It's a slightly tricky change to make because we need to version all existing part studios, but it can be done.
