Problem: Missing PoC on tesing `exposeClosureState` on simple JS file about nleak HOT 2 CLOSED

function exposeClosureStateInternal(filename: string, source: string, sourceMap: SourceMapGenerator, agentUrl: string, polyfillUrl: string, evalScopeName?: string, strictMode?: boolean): string {
  let ast = parseJavaScript(source, { loc: true });
  {
    const firstStatement = ast.body[0];
    if (firstStatement && firstStatement.type === "ExpressionStatement") {
      // Esprima feature.
      if ((<any> firstStatement).directive === "no transform") {
        return source;
      }
    }
  }

  const map = new Map<Program | BlockStatement, BlockScope>();
  const symbols = new Set<string>();
  let globalScope = undefined;
  if (evalScopeName) {
    globalScope = new ProxyScope(evalScopeName, strictMode === false);
    // In strict mode, newly defined variables cannot escape.
    if (strictMode) {
      globalScope = new BlockScope(globalScope, true);
    }
  }
  ast = ScopeCreationVisitor.Visit(
    EscapeAnalysisVisitor.Visit(ScopeScanningVisitor.Visit(ast, map, symbols, globalScope), map), map, symbols, agentUrl, polyfillUrl);
  return generateJavaScript(ast, { sourceMap });
}
