Dean gave the final word, I think, by reminding us of filter. some does not work because it will return the result of applying predicate-fn to the item, but we want the item "intact" in order to apply return-fn to it. But as said Meikel, and as I was implicitly implying in my final words by just saying "is it something like that you expected", the loop version is not so bad with performance considerations in mind.
