Further Vim9 improvements, possibly after launch:
- implement :class and :interface: See |vim9-classes| #11544
+ make default constructor use "this.member = void"
+ make public / default read access / private work for members.
+ string value of class and object in echo_string_core()
+ object empty(), len() - can class define a method?
+ tv_equal() should compare values, not identity.
+ garbage collection: set_ref_in_item(): Mark items in class as used ?
+ type() should return different type for each class?
+ how about lock/unlock?
- implement :type
- implement :enum
- Use Vim9 for more runtime files.
