Re: Functional Programming in Nim

[rect0x51]

Regarding that... what is currently the preferred way to do laziness in Nim? 
Hand-writing closure iterators works, but is there any established library? I 
know of [lazy](https://rawgit.com/petermora/nimLazy/master/doc/lazy.html) and 
[iterutils](https://hookrace.net/nim-iterutils/iterutils.html), but it's 
unclear if I should use one (which?) of them.
