I use Scala a bit - and it is OO/functional hybrid - it really steers you in the functional direction. I personally find it hard to reconcile OO with functional though (as in side effect free functional). I guess my personal (probably incorrect) experience with OO is all about mutability and state machines, whereas that is totally at odds with the rest of scala. So I end up not knowing what to do with the OO bit. I do like OO though, but I just can't seem to get it to fit together in my mind.
