I came across Nice a few months ago, but continued on my way. I’m not one to get into fringe languages and Nice seemed a bit academic. Xoltar’s Groovy features in Nice made me look again at the Nice site, and there are some interesting features there. Multiple return values is something that is sorely missing from Java, and I’d like to see that in Groovy. Syntax for optional method parameters would be a bonus, and I don’t think that’s something in Groovy yet either.
A little friendly competition never hurt anyone. Nice even has an Eclipse plugin as well, so it looks like the Nice 1.0 package may actually be worth considering for high-level programming needs.
