Browsing the source code, I came across something completely unexpected. I didn't know you could put code in structs like this sample from kamby/kamby.c struct KaNode *ka_add(struct KaNode *node, struct KaNode **env) { if (node->type == KA_STR && node->next->type == KA_STR) { struct KaNode *output = ka_str(node->str); strcat(output->str, node->next->str); return output; } return ka_num(node->num + node->next->num); }…
That's not a struct. It's a function called ka_add that returns a pointer to a KaNode
