patch 8.2.4257: Vim9: finding global function without g: prefix inconsistent Commit: https://github.com/vim/vim/commit/62aec93bfdb9e1b40d03a6d2e8e9511f8b1bdb2d Author: Bram Moolenaar <Bram@vim.org> Date: Sat Jan 29 21:45:34 2022 +0000 patch 8.2.4257: Vim9: finding global function without g: prefix inconsistent Problem: Vim9: finding global function without g: prefix but not finding global variable is inconsistent. Solution: Require using g: for a global function. Change the vim9.vim script into a Vim9 script with exports. Fix that import in legacy script does not work.
