The Common Language of Functional Programming

The names are oriented around the actual mathematical concepts, not oriented around the business. And so that's what made me think, okay, I mean, really, yes, when you're using a filter,. The essence of the filter is not the action of filtering, which is standardized and debugged, but this little usually Lambda or whatever function we pass that describes what we're filtering for. It seems like a place where it could easily leak in to the business domain.
