提供一个能针对表达式进行编译的接口

现在只有DefaultExpressEvalService.eval(ctx, criticalExp)，这个接口必须要传入 上下文，而我希望能有个类似这样的接口：DefaultExpressEvalService.eval(criticalExp)

Start at DefaultExpressEvalService.eval(ctx, criticalExp) and inspect how the context argument is used. Determine the intended behavior for eval(criticalExp), then verify that the new entry point preserves the existing expression-evaluation behavior and is covered by the repository's existing tests.
