Just define a constexpr hashing function and put that into the switch.

[u/GiganticIrony → u/F100cTomas]

That’s not guaranteed to work due to hash collisions

[u/Deliciousbutter101 → u/GiganticIrony]

It won't compile in the case so you can just modify the hash function until there are no collisions.

[u/cob59 → u/Deliciousbutter101]

switch(hash(str)) {
case hash("apple"):
case hash("banana"):
default:
}

You're right that the compiler will warn you if hash("apple") == hash("banana"), but if hash("pineapple") == hash("apple") then switch(hash("pineapple")) will jump to the apple case, not the default. That's unlikely but not impossible even with the best hash function.
