Closures:

This chapter covers Groovy Closures. A closure in Groovy is an open,

anonymous, block of code that can take arguments, return a value 

and be assigned to a variable. A closure may reference variables 

declared in its surrounding scope. In opposition to the formal 

definition of a closure, Closure in the Groovy language can also 

contain free variables which are defined outside of its surrounding scope.

While breaking the formal concept of a closure, it offers a variety of 

advantages which are described in this chapter.

Syntax:

{ [closureParameters -> ] statements }
