+ *
+ * function walk(ctx: Lint.WalkContext): void {
+ *     let isInFor = false;
+ *     ts.forEachChild(ctx.sourceFile, function cb(node: ts.Node): void {
+ *         switch (node.kind) {
+ *             case ts.SyntaxKind.Break:
+ *                 if (isInFor) {
+ *                     ctx.addFailureAtNode(node, "!");
+ *                 }
+ *                 break;
+ *             case ts.SyntaxKind.ForStatement: {
+ *                 const old = isInFor;
+ *                 isInFor = true;
+ *                 ts.forEachChild(node, cb);
+ *                 isInFor = old;
