How to comment List item?

Question

There are times I want to comment List items:

let test_data = [
      \ " description in comment
      \ complicated_data0
      \
      \ " description in comment
      \ complicated_data1
      ...
      \ ]

----
result error:

E114: Missing quote: " description in comment 0 ]

E114 is thrown as it's missing the enclosing".

What's the common workaround ?

Since patch 8.1.0369 you can comment continuation lines. However, you must follow the "\ syntax:

let test_data = [
      "\ description in comment
      \ complicated_data0
      \
      "\ description in comment
      \ complicated_data1
      ...
      \ ]

Prior to that, you would need to split the list up into pieces:

" description in comment
let test_data = [
      \ 1,
      \ ]
" description in comment",
let test_data += [
      \ 2,
      \ ]
