Vim错误E745在`neosnippet`中创建`Latex`片段时'使用列表作为数字'

Question

我使用neosnippet为latex模板创建片段。这段代码相当长，当我尝试展开代码段时，我一直在收到奇怪的错误E745 Using a List as a Number。

以下是neovim发布的错误消息。

[dein] Error occurred while executing hook: neosnippet.vim 
[dein] Vim(let):E745: Using a List as a Number 
Error detected while processing function <SNR>346 snippets_expand ... 
Line 11 
E15: invalid expression: 
E15: invalid expression 

实际的代码片段本身在下面 - 它很长。现在，当我从片段文件中取出这个长片段时，所有其他片段都可以正常工作。所以它似乎在某个地方我正在使用我不应该使用的角色或什么的。或者可能是某些东西没有正确逃脱，等等。

我所有的其他胶乳片段都能正常工作，但也有短得多。有没有人有任何想法，为什么这个片段造成这么多麻烦？

这是乳胶片段。

好的，我与开发人员交谈过，他表示问题与本文档中的反引号有关。

\newcommand{\forwards}{\mbox{````$\Longrightarrow$''}\xspace} 
\newcommand{\backwards}{\mbox{````$\Longleftarrow$''}\xspace} 

我更新了neosnippet插件，也改变了latex代码。现在事情工作正常。
