What's wrong with Groovy 
Despite what
Paul Graham writes about productivity, I lost it. I've been using and loving
Groovy for some time now, but despite it's powerfull features like closures and short syntax, I'm less productive than with Java. In Java I have a great IDE like IDEA, which makes me so much more productive with syntax highlighting, smart code completion, debugging, automatic imports and refactoring. With Groovy I have nothing like that (and I won't use Eclipse for other reasons). It's very painful to write code without such support. This made it clear to me that I'm more productive with Java/IDEA than with a dynamic scripting language.
Stephan needs IDEA Groovy plugin badly. Or was this wizard and food?
