and and or keywords (just to make it slightly clearer when you're working with the & (AND) and | (OR) operators but also just for better readability in general), I could probably put interfaces into my language (even though in my blog, I said I wouldn't).I'm wondering how I'd be able to cleanly communicate whether an interface's function is "pure" or not.
interface Drawable {
void draw() pure; // Something like this instead of `= 0;` ?
};
