patch 9.0.2076: Vim9: No support for type aliases Commit: https://github.com/vim/vim/commit/ec3cebbd2b6b7583d2f683f5e66345163ec122aa Author: Yegappan Lakshmanan <yegappan@yahoo.com> Date: Fri Oct 27 19:35:26 2023 +0200 patch 9.0.2076: Vim9: No support for type aliases Problem: Vim9: No support for type aliases Solution: Implement :type command A type definition is giving a name to a type specification. This also known type alias. :type ListOfStrings = list<string> The type alias can be used wherever a built-in type can be used. The type alias name must start with an upper case character. closes: #13407 Signed-off-by: Christian Brabandt <cb@256bit.org> Signed-off-by: Yegappan Lakshmanan <yegappan@yahoo.com>
