patch 8.2.0323: Vim9: calling a function that is defined later is slow Commit: https://github.com/vim/vim/commit/7eeefd4a395fe3d7c7a2a0879467cf7ed4c29fe6 Author: Bram Moolenaar <Bram@vim.org> Date: Wed Feb 26 21:24:23 2020 +0100 patch 8.2.0323: Vim9: calling a function that is defined later is slow Problem: Vim9: calling a function that is defined later is slow. Solution: Once the function is found update the instruction so it can be called directly.
