It's indistinguishable from a cons, which is bad for many reasons
explained at length. Weren't you involved in "symbol-with-pos"?
It's a similar object with a unique type. So it's going to need
more arguments than just being scared of generic functions.
Noone is advocating for calling generic functions from C or
preloading them, etc, so don't worry about it.
