I ran across this thread while searching for various functionality, and wondering where to submit a PR if I add some.
[Changes in sequtils (forum post)](https://forum.nim-lang.org/t/1333) I'm curious if anyone knows if these suggested changes and additions are still under consideration, or if it was decided to let them remain in an external repository (nimLazy), and what are people using if they want any of these features? There seem to be some great relevant packages out there all overlapping to a large degree, but not interoperable: [nimLazy](https://github.com/petermora/nimLazy), [itertools](https://github.com/narimiran/itertools), [pipe](https://nimble.directory/pkg/pipe), [mangle](https://github.com/baabelfish/mangle), and maybe others I didn't find.
