+- At the Vim9 script level, keep script variables local to the block they are
   declared in?  Need to remember what variables were declared and delete them
   when leaving the block.
 - Implement { } block at the script level.
+- Use the line number argument with assert_fails() in many more tests.
 - In autocmd: use legacy syntax, not whatever the current script uses?
 - need to check type when a declaration specifies a type: #6507
 	let nr: number = 'asdf'
 - Make sure that in vim9script a function call without namespace only finds
   the script-local function, not a global one.
+- Make sure that where a callback is expected a function can be used (without
+  quotes). E.g. sort() and map().  Also at the script level.
 - Make map() give an error if the resulting type is wrong.
   Add mapnew() to create a new List/Dict for the result, which can have a
   different value type.
