I’ve just gotten word from the current ‘maintainer’, who has basically all-but-said that he has no desire to do so. The current stuff is both dated (not even R6RS is supported, forget R7RS!) and flawed (lots of line alignment issues all over the show), and badly needs some love and attention.
Is there anyone out there both willing and able to improve life for Scheme users on (Neo)vim? I’m posting this in the hope someone might pick up this flag.
