patch 9.0.1906: Vim9: Interfaces should not support class methods and variables
Problem: Vim9: Interfaces should not support class methods and
variables
Solution: Make sure interface follow the interface specification
Vim9 interface changes to follow the new interface specification:
1) An interface can have only read-only and read-write instance
variables.
2) An interface can have only public instance methods.
3) An interface cannot have class variables and class methods.
4) An interface cannot have private instance variables and private
instance methods.
5) A interface can extend another interface using "extends". The
sub-interface gets all the variables and methods in the super
interface.
That means:
- Interfaces should not support class methods and variables.
- Adjust error numbers and add additional tests.
- Interface methods can be defined in one of the super classes.
- Interface variables can be defined in one of the super classes.
and instance variables can be repeated in sub interfaces.
- Check the class variable types with the type in interface.
