what am I doing wrong I also cant compile the code The funct kotlinlang #getting-started

inline fun <V, reified T> enum(name: String, description: String, required: Boolean = false) where T : EnumWithValue<V>, T : Enum<T> {
        val values = enumValues<T>()
        when(values[0].value) {
            is Int -> int(name, description, required) {
                values.forEach { enum -> choice(enum.name, enum.value as Int) }
            }
            is Double -> number(name, description, required) {
                values.forEach { enum -> choice(enum.name, enum.value as Double) }
            }
            is String -> string(name, description, required) {
                values.forEach { enum -> choice(enum.name, enum.value as String) }
            }
            else -> throw IllegalArgumentException("Enum values must be of type Int, Double or String")
        }
    }

Maybe because

enum

is a reserved keyword. Is it the same if you rename the function name and all inner

enum

params to something else?

Same problem, also the function used later to get these values back has the same problem

A while back I had a problem with official builders (I have no idea what an OptionBuilder is) and reported an official tracker on the youtrack. Can you explicitly type the builder if thats a thing?

I think its a problem with the generics all other functions in this builder scope work fine

But I have no idea whats wrong with the generics

Okay the problem was that the method required 2 type parameters. But weird error. Tho shouldn't Kotlin like know what the type is because the first parameter (T) has the value type?

where T : EnumWithValue<V>, T : Enum<T>

Because always doing enum<Int, ComponentType> seems a bit redunant?

or is this possibly a bug?

This is not a compile error, it's an error in the compiler – I'd say it's probably a bug.
