In my opinion this is a clear ad-hominen attack from Obie against Alex, and one that should not be appreciated.

I am not a fan of scala, but I say lets wait and see what happens, as we all should know by now, in theory Ruby should scale as much as scala, but maybe in practice we come up with different results! As is there is a difference between what you should be able to do, and what you can really do.

Alex is obviously trying what he thinks he can, not what other thinks he should be able to do! which is of course just a theory
