Comments on: Lazier function definitions by merging partial values http://conal.net/blog/posts/lazier-function-definitions-by-merging-partial-values Inspirations & experiments, mainly about denotative/functional programming in Haskell Sat, 26 Sep 2020 21:06:12 +0000 hourly 1 http://wordpress.org/?v=4.1.17 By: Conal Elliott » Blog Archive » Lazier functional programming, part 1 http://conal.net/blog/posts/lazier-function-definitions-by-merging-partial-values#comment-322 Mon, 13 Sep 2010 22:18:59 +0000 http://conal.net/blog/?p=76#comment-322 […] reading. (The reading is less straightforward when patterns overlap, as mentioned in Lazier function definitions by merging partial values.) In a non-strict language like Haskell, there are three distinct boolean values, not two. Besides […]

How can we mix it in with the sum of recursive calls to integral? We can use (⊔) (least upper bound or “lub”), which is perfect for the job because its meaning is exactly to combine two pieces of information. See Merging partial values and Lazier function definitions by merging partial values. […]

As a language extension, it will probably be easier to prove totality while retaining nearly identical syntax to existing pattern-matching functions.

If true, I would consider this a very important theorem. If I have some idle brainpower (unlikely) I’ll play with it a bit.
