Re: Wisp as shipped language in Guile?

Hi Arne!
Personally, I'd like to see many languages on Guile. But I prefer  maintain mine, guile-lua-rebirth and a new shell language(undone) as an external package. 
GNU official project reviews contributions too strictly, it's good for the quality and free software ethics, but too difficult for new contributors as a compromise.
I will be happy to see if wisp accepted to be in Guile core. But if not, it's not a big deal IMO, especially when we have Guix now.
What do you think?

Best regards

Any word on this? We have ecmascript, we have elisp, we have brainfuck,
why not wisp — which is finished and stable and does not require any
non-sexp-scheme code in Guile?

Best wishes,
