patch 9.0.0632: calling a function from an "expr" option has overhead Commit: https://github.com/vim/vim/commit/87b4e5c5db9d1cfd6f2e79656e1a6cff3c69d15f Author: Bram Moolenaar <Bram@vim.org> Date: Sat Oct 1 15:32:46 2022 +0100 patch 9.0.0632: calling a function from an "expr" option has overhead Problem: Calling a function from an "expr" option has too much overhead. Solution: Add call_simple_func() and use it for 'foldexpr'
