Then you can just do

class Foo
{
final:
    // methods...
}

or

class Foo
{
final
{
    // methods...
}
}

And even if you couldn't do that, you could always mark each function with
final individually.

Yes. final should probably be the default, but unfortunately, that's not the
choice that was made early on, and it was decided later that the change
wasn't worth the breakage. But it can be worked around easily enough.
