Doesn't it just work using numeric indices?

regarding :component-should-update, (fn [old-argv new-argv] returns a normal map with :props from old-argv but then a vector with a function followed by a map with :props in new-argv. if i want to prevent a component from updating based on an old key vs. a new key, can i not use a simple compare?

(i want to ignore a prop unless another prop has changed)
