Hello Guilers,
I'm pleased to announce Guile SRFI-146 0.1.0: https://inqlab.net/git/guile-srfi-146.git/tag/?h=v0.1.0 Guile SRFI 146 provides bindings to SRFI 146 (Mappings). SRFI 146 provides two purely functional mapping data structures: One that uses an ordering of keys and another that uses a hash on keys. The implementations use red-black trees and hash array mapped tries (HAMT). The library re-uses the SRFI sample implementation with some minor Guile specific fixes and optimiztions. The SRFI test suite has also been ported. The package has been submitted to Guix so you should be able to start some purely functional hacking very soon (https://issues.guix.gnu.org/57055). Bug reports, fixes and patches are very welcome. Best regards, pukkamustard
