Nice is a very attractive new Java-like language for the JVM. Xoltar has nice things to say about Nice, the language. I'm more than a little enchanted: much better type safety than Java, multimethods, closures, parametrics types, named parameters, tuples. Wow! And unlike Groovy, it really does look like Java after some weight-lifting. (I'm sorry, but I'm too attached to
;. Call me a "C" bigot, but it just looks wrong otherwise.)
I'm eager to give Nice a spin and perhaps use it a project. And the comparison of Nice and Groovy really isn't that fair — Nice is still pre-compiled into bytecode like Java, not scriptable like Groovy. There's plenty of need for both.
