Support for generic type parameters on properties (get/set)

Would it be possible to support generic type parameters on properties, specifically when using get and set accessors?
For example:
```haxe
public var value(get, set):T;

private function get_value():T;
private function set_value(v:T):T;
```
Since property accessors are compiled as functions, this will enable flexible, type-safe patterns without needing Dynamic or class-level generics.
