Ruby modules make things like passing a database connection or other dependencies to various objects much easier while allowing for separation of concerns. Does Groovy support a similar functionality? And if so what is it called?
Does Groovy have support for something like Ruby Modules?

In ruby modules are used either as mixins or to namespace a class (e.g.
Net::HTTP).To mixin the behavior you can use @mixin annotation. like examples here http://groovy.codehaus.org/Category+and+Mixin+transformations.
To namespace, groovy uses same mechanism as java i.e. using packages (e.g.
groovy.sql.Sql).I am not sure if that answered your question or not. But for dependency injection, while its common to do it mixin way in ruby (or even in scala/play), I have not seen it done a lot using
@mixinin groovy. Usually a DI container like spring is used.
