Or in C# with Linq:

int sum = intList.Aggregate((a, b) => a + b);

Nice examples,

I would note that with ecmascript your example would be something like:

var array = [ 1, 2, 3 ]; reduce(array, function(n1, n2){ return n1 + n2; });

but maybe the strong typing will make others feel better.

I have proposed an alternative closures proposal C3S:

Your examples in C3S are:

final list = ArrayList.new( 1, 2, 3 );
reduce list, method( x1, x2 ) { x1 + x2 };

with lock, method { out.println "Hello" };

with File.open( "foo.txt", "w" ), method( file ) { doSomething };
