Nope. Same error, even after blowing away m2 and rerunning the basic

Thanks Greg. Your points on the compiler are well taken. A compiled language
with higher order functions, general functional programming paradigms and
all the rest that Scala has is great. I also like Haskell, but like you, I

This was just what I needed to push me over the edge. Actually I was there

For my money Rails is somewhat more mature than lift, but lift is on a
trajectory to overtake Rails feature-wise and is certainly already there
performance-wise. The real issue, to me, is Scala vs Ruby. Quite apart from

I guess JGroups is another alternative here, it's a bit lower level, but
