patch 8.2.0818: Vim9: using a discovery phase doesn't work well Commit: https://github.com/vim/vim/commit/822ba24743af9ee1b5e7f656a7a61a38f3638bca Author: Bram Moolenaar <Bram@vim.org> Date: Sun May 24 23:00:18 2020 +0200 patch 8.2.0818: Vim9: using a discovery phase doesn't work well Problem: Vim9: using a discovery phase doesn't work well. Solution: Remove the discovery phase, instead compile a function only when it is used. Add :defcompile to compile def functions earlier.
