Not really. Actually, however, there is a recent survey that shows that Groovy is the second most popular language on the JVM, behind Java. Myself, I use Scala, and would like to learn Frege.
There's something wrong when a testing framework hacks into a language parser to make the language statement labels have special meanings like function names do, and overload the `|` operator in expressions so data will appear as a table in the source code. "Lovely" isn't the word for that sort of thing.
