I don't know that I'd call Groovy a dialect of Ruby. Sure, it's features are _inspired_ by Ruby but there are many very significant differences. No magic undeclared variables as a simple example. Another example is the categories feature, which Ruby doesn't really have. Not to mention that the syntax is completely different.
