patch 9.0.1909: Vim9: problem calling class method from other class Commit: https://github.com/vim/vim/commit/00cd18222ee1551c65228e9556c158624507fc7a Author: Yegappan Lakshmanan <yegappan@yahoo.com> Date: Mon Sep 18 19:56:49 2023 +0200 patch 9.0.1909: Vim9: problem calling class method from other class Problem: Vim9: problem calling class method from other class Solution: Fix this problem, fix readonly object access, update error messages. Calling a class method from another method without the class name prefix doesn't work properly. A readonly object variable is modifiable outside the class using a nested object assignment. Remove the unused E1338 error message. Update error messages. closes: #13116 Signed-off-by: Christian Brabandt <cb@256bit.org> Co-authored-by: Yegappan Lakshmanan <yegappan@yahoo.com>
