Groovy 1.8-beta-2 gets ability to compose closures together to form a new closure.

The Groovy team have announced two new releases: Groovy 1.7.5 and Groovy 1.8-beta-2.

Groovy 1.8-beta-2 introduces closure composition. This is the ability to compose closures together to form a new closure, which chains the call of those closures. It also features an extension of the command expression notation, which allows the developer to omit dots and parentheses for chained methods calls. This release also provides a mechanism for Global AST Transformations, which allows them to define a file extension for the Groovy sources they should be applied to.

The Groovy 1.7.5 release adds multiple file extensions support in the compiler and adds synthetic bindings to Jlist. It also provides a stub generator testing infrastructure and fixes a list of bugs. Please see the Release Notes for more information.
