+/**
+   File Name:          11.12-4.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.
