A word used to describe something

I wanted to respond to Danny Coward's blog entry on Java 7, but his spam detection seem somewhat too rigourous, so I'm making my comments here

Over the last week or so I've spent some time evaluating the various closure discussions that are floating about.

So, I sat down to write some code. Most of the situations where I've longed for some sort of closure syntax are in iteration contexts - searching lists, filtering lists, etc. - so my first test scenario was just that. I wanted to iterate over a list of integers, and negate each one to produce a new list. Then I wanted to iterate over that list and print out each number.
