lazy functional programming can be used for better modularity. A more precise title for the paper would be "Why Lazy Functional Programming Matters".
This is Oleg. He's perfectly aware of the paper. The point he's making is not that laziness is bad, but that it shouldn't be the default. And if you note the recent work on -XStrict, there are good arguments about bolting laziness on top of strictness and not doing a nasty -- and thus necessarily heroic -- shoehorn in the reverse direction. See: https://www.reddit.com/r/programming/comments/3sux1d/strict_haskell_xstrict_... However, the record remains that Oleg has offered little by way of elegant bolting. His lazy programs based on a strict language tend to be cluttered with lazy and force functions that uglify previously elegant code. His arguments would persuade many more folks if, for instance, he could offer lazy-over-strict translations of Doug McIlroy's power serious one-liners with no loss in elegance: http://www.cs.dartmouth.edu/~doug/powser.html -- Kim-Ee
