[bug#61070] gnu: packages: Add guile-simple-iterators.

["J. Sims via Guix-patches" via <guix-patches@gnu.org>]

[-- Attachment #1.1: Type: text/plain, Size: 226 bytes --]

Hello,

guile-simple-iterators is a collection of macros to provide iteration inspired by Racket in Guile. I use them and find them delightful, so I thought other Guix users would appreciate ready access to them.

Thanks,
Juli
