You can also peruse SICP for knowing about how lazy evaluation works. The explanations are nice. It is in lisp, though. https://mitpress.mit.edu/sicp/full-text/book/book-Z-H-24.html#%_sec_3.5 On Mon, Aug 17, 2015 at 2:12 PM, akash g <akaberto@gmail.com> wrote:
Hi Rein,
The initial version which the OP posted doesn't have a terminal value. The OP had posted the version that he'd wanted clarification on.

It will absolutely work. Lists can be infinite in Haskell and infinite lists are productive:

Not a problem. And I should have thought about what you wanted too.
This version will give you an infinite list of odd numbers from 3.

Sorry, I wrote a wrong function, the correct version is:
oddsFrom3 :: [Integer] oddsFrom3 = 3 : map (+2) oddsFrom3 --

I know that it will evaluate to a list of odd numbers >= 3, but how?
Thanks, anyway. --
