Ruby.evalScriptlet介绍

[英]Evaluates a script under the current scope (perhaps the top-level scope) and returns the result (generally the last value calculated). This version goes straight into the interpreter, bypassing compilation and runtime preparation typical to normal script runs.
[中]在当前作用域（可能是顶级作用域）下计算脚本，并返回结果（通常是最后计算的值）。这个版本直接进入解释器，绕过编译和运行时准备，这是正常脚本运行的典型情况。
