patch 8.2.1682: Vim9: const works in an unexpected way Commit: https://github.com/vim/vim/commit/dbeecb2b6bc5bf90b7345807e0a313fe890a7c7b Author: Bram Moolenaar <Bram@vim.org> Date: Mon Sep 14 18:15:09 2020 +0200 patch 8.2.1682: Vim9: const works in an unexpected way Problem: Vim9: const works in an unexpected way. Solution: ":const" only disallows changing the variable, not the value. Make "list[0] = 9" work at the script level.
