+    File Name:          expression-001.js
+    Corresponds to:     ecma/Expressions/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.
