Rich Hickey: Reducers - A Library And Model For Co...
If you use a mapped reducible twice, does that evaluate the function on each element twice?

If you call reduce on it twice, then sure, it would do all the work twice.

Jules's point is that the map is done twice, which it is. If you don't want that, you can reduce into a collection and then reduce the collection twice.
