Yeah. I would like "Hello $name" to compile to something like a StringTemplate object (if needed, it should also still be assignable to String obviously).
More hand-wavy API:

interface StringTemplate {
    val placeholders: List<String>
    fun getValue(placeholder: String): Any?
    fun toString(mapper: (@ParameterName("name") String, @ParameterName("value") Any?) -> Any?): String
}

Tiny remark: any reason to use @ParameterName? Isn't there real symtax for this?

[diesieben07]

No there isn't afaik. But I am not sure

[diesieben07]

But I already have a better idea for the API anyways.

Just checked, you can give lambda parameters names: fun foo(mapper: (name: String) -> Unit) {}
