¿Para qué sirve el complemento L9 vim?

Question

Recientemente me encontré con este extraño complemento para Vim y no pude entender cuál es su uso.

Casi no está documentado y nobdy realmente habla de ello, pero parece importante para algunos otros complementos.

Todo lo que encontré está aquí:

http://www.vim.org/scripts/script.php?script_id=3252

y

https://github.com/eparreno/vim-l9

pero solo dicen "Es una biblioteca" y "Ver el código fuente".

Alguien sabe para qué sirve esto, si debería tenerlo, para qué propósito, o si puedo simplemente eliminarlo hasta que alguna dependencia no esté satisfecha en algún otro complemento.

Me he dado cuenta de referencias a L9 en un par de lugares, recientemente de Vundle. Es cierto, no está documentado desde el principio. Pero hay comentarios decentes en el archivo fuente principal, autoload/l9.vim . Es un conjunto de funciones de utilidad de propósito general. Aquí está la mayor parte de su API, que aumenta el tratamiento de Vim de listas, números, cadenas, líneas, rutas, archivos, búferes, ventanas, búsqueda y más:

" returns false if the caller script should finish.
" a:vimVersion: if 0, don''t check vim version
" a:l9Version: same rule as v:version
function l9#guardScriptLoading(path, vimVersion, l9Version, exprs)

" Removes duplicates (unstable)
" This function doesn''t change the list of argument.
function l9#unique(items)

" [ [0], [1,2], [3] ] -> [ 0, 1, 2, 3 ]
