Groovy is dynamically typed, not statically typed. Though a month ago Springsource/EMC hired someone to build a static type checker (called Grumpy) for Groovy (http://www.jroller.com/melix/entry/groovy_static_type_checke...) with the usual solicit for free labor by spinning the "open source" tale.

Presumably they heard about Xtend from the same place Jboss/Redhat and Jetbrains did. Hence the recent avalanche of announcements regarding Ceylon, Kotlin, and Grumpy.
