many known java ppl
“Gilad Bracha, Neal Gafter, James Gosling and Peter von der Ahé”

To whom never worked with closure:

http://martinfowler.com/bliki/Closure.html

Example in ruby:

[1,2,4,5].each { |item| puts item }

Example in java (proposed)

Before closure:

void doit(API api) {
api.doRun(new Runnable(){
public void run() {
snippetOfCode();
}
});
}

After closure:

void doit(API api) {
api.doRun(() { snippetOfCode(); });
}
