Thank you Jan-Peter! This looks really promising, and I’d love to contribute.
I’m only vaguely familiar with Scheme so I’ll probably take a bit of time to get my hands dirty with that. Would it be OK to bug you with questions every now and then? Is this list a good place, or should I just email you privately? I promise I won’t abuse your kindness :-) Alex > On Oct 16, 2018, at 2:04 AM, Jan-Peter Voigt <jp.vo...@gmx.de> wrote: > > Hello Alex, > > you don't have to apologize for this question!
