/**
    File Name:          11.12-2-n.js
    ECMA Section:       11.12
    Description:

    The grammar for a ConditionalExpression in ECMAScript is a little bit
    different from that in C and Java, which each allow the second
    subexpression to be an Expression but restrict the third expression to
    be a ConditionalExpression.  The motivation for this difference in
    ECMAScript is to allow an assignment expression to be governed by either
    arm of a conditional and to eliminate the confusing and fairly useless
    case of a comma expression as the center expression.
