Hi,

As far as I'm concerned, definetely not! I also think that it would be great if, for 4.7, Jon could handle the library issues with EBO by exploiting it. I only meant to say that something seems to me more fundamentally wrong at the design level about 'final' vs EBO, my hope is that for 4.8 we'll have a longer term stable solution based on a ISO Committee position.
