I kind of want to argue that the being pretty nuts part is fundamental and somewhat excludes being a business-as-usual-“business-logic”.
@screwtape Someone really ought to do a survey, because I suspect that there is a higher-than-baseline percentage of people in the Lisp communities who are Autistic, ADHD, and/or Trans/Queer people, and that could serve as another bit of evidence to your “being pretty pretty nuts.”
I like to think that people in the Autism/ADHD demographic have a tendency to gravitate toward simplicity and mathematical beauty, and this is part of the reason why they tend to gravitate toward Lisp.
“Making Scheme object-oriented is a sophomore homework assignment. On the other hand, adding object orientation to C requires the programming chops of Bjarne Stroustrup.” — Rudolf Winestock
Well, there is also GObject, which is an object oriented programming system for C based on the C preprocessor, though it is definitely not a sophomore homework assignment to construct somehting like that. There is also the Vala programming language, which transliterates to C.
