" large_list_literal.vim — a List literal with more than 255 elements.
" A single VIML_MAKE_LIST bytecode op carries its element count in a u8
" (max 255); VimL puts no limit on a List literal. The compiler builds an
" oversized literal in chunks of 255 concatenated with `+` (List+List),
" which must yield the identical List — same length, same order across the
" 255/256 chunk seam. (Vim corpus: autoload/clojurecomplete.vim,
" autoload/haskellcomplete.vim ship ~700-element completion lists.)
