I've never heard of a language that overloaded member variables, and given how class polymorphism works, I don't see how it would even be possible without making it so that all accesses to a variable actually call a function to access it, which would needlessly inefficient (polymorphism works by looking up the correct function in the class' virtual table, and the call site isn't going to know at compile time what class it's actually operating on, so all of that has to be done at runtime). And if you really want something approximating overriding variables, then you can just use property functions to access the variable rather than accessing it directly, and then you can override the property functions.
In Scala all public instance variables are implemented as methods, if I recall correctly.
