Are there any plans to add type bounds to Vala generics?
This would allow something like (e.g., using Java's keyword):
public int get_length<T extends string> (T val) {
return val.length;
}
I.e. the T is qualified to be a subclass of 'string' (not that this is
necessarily possible in Vala), and thus the compiler knows that anything
that can be done to a string can be done to an instance of T.
