We had that idea recently, not sure it is what @amanda.hinchman-dominguez wants, but anyway here it is. We dubbed it Compile-Time Reflection (CTR).
The idea is that if you write code like you’re using reflection (all pseudocode):

for (property in MyClass::class.properties) { … }

The compiler knows statically which properties are there and can unroll the loop. Then, if you add

for (property in MyClass::class.properties) {
   when (property.type) {
      Int::class -> callInt(property.name, property.get())
      … other types …
   }
}

While unrolling the loop compiler can eliminate all the cases and insert just specific calls for each property, inserting constant strings for property names, insert direct property access for get, etc. There are lots of caveats even in this naive idea. But still, that could be cool some day in the future 🙂
