我正在为编程入门课程创建参考文档。作为其中的一部分，我将提供语法定义和语法示例。
为了编写此代码，我希望使用如下的 LaTeX 语法：
\begin{myenv}
% syntax-highlighted syntax definitions
<stuff> <here> <type> <name>(<args>) { <body> }
\tcblower % or better yet, some marker \StartExamples.
% Escaping with @...@ would obviously be ok here.
% syntax-highlighted examples of syntax being defined.
public static void Main(string[] args) { ... }
\end{myenv}
这将给我一个可爱的两部分 tcolorbox，其中虚线穿过框将抽象定义与具体示例分开。语法当然是解决方案的次要部分……
遗憾的是，如果我实际上\tcblower在上面使用（在里面转义@@），我会得到一个吨錯誤數字：

我怀疑这里的问题也出在群体层面（参考) 假设\tcblower最终位于 内\PYG{esc}{\tcblower}。我以前知道\PYG最终位于何处，但如果有人说它在扩展后不是“裸露的”，我会相信它，因为 tcolorbox 可能正在期待。
如果我不转义对 的调用\tcolorbox，它将被解释为 C# 代码并显示一个红色方框，表示语法错误。因此，转义它是非常必要的。
