For what its worth , the cache locality of Vec<Box> is terrible in general, i feel like if youre iterating over a large array of things and applying a polymorphic function you're making a mistake.

Cache locality isnt a problem when youre only accessing something once though.

So imo polymorphism has its place for non iterative-compute type work, ie web server handler functions and event driven systems.
