You really don't have enough appreciation for Option::map until you try to do the same thing in C++ (while keeping everything on the stack)

Sorry, left out some context. Try to do the same thing in C++ with pointers only.

Got a code snippet? :v

Already left work but here's something I'm typing on my phone: void dostuff(Bar &bar) { // Foo need not last after this function Foo f(bar); // ... } I want a way to make bar into a pointer that can be null. I want f to become a pointer that is null if bar is null.

Oh and I want everything to stay on the stack. So far I'm having to use new/delete which really sucks. I can't even use a smart pointer because that has a different type.

Why not use a unique pointer with a custom Deleter and a ::pointer to keep the types compatible? You could also do some magic with placement new

That would definitely solve the problem of having to add delete everywhere (this is very branchy code), but it doesn't help the fact that it's heap allocated. I'd be adding a lot of complexity without really getting the code I'm after

(I'm fairly confident that there is no nice way to express what I want in C++ so I'm pretty resigned to my new/delete solution even though it isn't great)
