I think the examples shown here don't really show how it can help- the real win for me is if you already have a function to filter over (like "article.isJava()" or something) it becomes much clearer. It also is eye opening to see or higher order functions like pluck or flatmap that build off these blocks. Edit- there is a good flatmap example there that I glossed over when first reading. It looks like Java even has serviceable syntax for passing around lambadas like that now too, that is cool.
