We sort of have a sort_by method in Sort::Maker. But I've never liked the api. There is no denying that an ST is a scary sight to a new programmer not familiar with the idiom. I'd argue it should be wrapped in a sub for clarity most often.

I like the PBP argument for using List::Util and List::MoreUtils functions such as any rather than idiomatic uses of grep. It makes your intention clear, and prevents you from thinking in syntax - no matter how comfortable and familiar that syntax is.

update: added some words for clarity
