Groovy’s dynamic nature, its ability to execute code passed in as a command line

argument, the presence of closures , and its general “less is more” approach to syntax

are all factors in allowing us this syntactic freedom. However, the biggest driver is ease

of use, both in writing and reading code. Consider this line:

[6, 3, 4, 8, 2, 7].findAll{ it % 2 == 0 }.each{ println it }

We are back to nding the even numbers in an array, this time printing 6, 4, 8, and
