To: vim_dev@googlegroups.com Subject: Patch 8.2.0818 Fcc: outbox From: Bram Moolenaar Mime-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ------------ Patch 8.2.0818 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.
