patch 8.2.4390: Vim9: list from declaration with inferred type not set Commit: https://github.com/vim/vim/commit/e88c6b7a5d8b24f8aa9a3e976b78654bae293ae4 Author: Bram Moolenaar <Bram@vim.org> Date: Tue Feb 15 15:37:11 2022 +0000 patch 8.2.4390: Vim9: list from declaration with inferred type not set Problem: Vim9: list from declaration with inferred type does not set the type on the value. Solution: When inferring the type in a variable declaration also set the type of the list or dictionary. (closes #9705) Do not set the type when the member is "any".
