Has anyone had a play with generics in the JDK1.5 beta-release and/or
knows the answer to this:

If I have the following:

// immutable
interface Address
{
    String getStreet() { ... }
    ...
}

// mutable
class MutableAddress implements Address
{
    String getStreet() { ... }
    void setStreet( String street ) { ... }
}

then using generics I could define this:

    private List<MutableAddress> list;

but could I 'down-cast' this list to do the following:

    List<Address> getList() { return list; }

i.e. the client will only get the immutable base-class.

Any ideas?
