VIM应该是编辑器，而不是外壳或通用编程平台。因此，其“文件系统” -API非常有限（考虑到某些功能在许多不同的OSS之间也可能无法运行）。因此，当您需要外壳时，只需调用它

:!ln -s ~/foo ~/bar
:"or like this
:call system('ln -s ~/foo ~/bar')

，这是“纯Vimscript”，只是它取决于外部工具并且慢。

在Neovim，还有Lua Engine的内置。当然，lua与vimscript不同，但是它已经存在，也可以从vimscript调用。而且，如果您缺少一些功能，则可以使用以通用编程语言编写的二进制模块（IE动态库）进行扩展，例如C。

当然，VIM中还有其他一些“语言接口”不想加载整个Python发动机只是为了避免单个壳调用。

Vim is supposed to be an editor, not a shell or general purpose programming platform. Therefore its "filesystem"-API is quite limited (consider that some features may be even non-portable between many different OSes Vim may run on). So when you need shell just invoke it

:!ln -s ~/foo ~/bar
:"or like this
:call system('ln -s ~/foo ~/bar')

And this is "pure VimScript" except it depends on external tool and is slow.

In Neovim there's also Lua engine builtin. Sure, Lua is different from VimScript, but it's already there and could be invoked from VimScript too. And in case you're missing some functionality, you can extend it with binary modules (i.e. dynamic libraries) written in general purpose programming language, such as C.

Of course, there are also some other "language interfaces" in Vim but you probably don't want to load the whole Python engine only to avoid a single shell call.
