// 1. No new  syntax for non-TCP functions.
//
// This approach does do include a shorter syntax for regular functions, so if a classic JS function
// is what you want you use the classic long form function expression:

a.some(function (x){
    if (invalid(x))
        return true;
    console.log(x);
});
