Hi guys! Is there any way of to implement `invoke` operator to initialize an `enum class`? I tried as an extension function, but the Intellij doesn't seem to see the constructor...

What do you mean “initialize an enum class”

```enum A() { B, C }

operator fun A.invoke(s: String) = if (s == "something") A.B  else A.C```

Your operator is defined on instances of A, so it would require an already available instance.

To call something like `A("something")`, you need either to use the companion object invoke, or a factory function:

```
fun A(s: String) = if (s == "something") A.B else A.C
```

Oh, that makes sense! I guess that was a confusion because extension functions are essentially `static` members, but forgot they're called on the actual instance... :see_no_evil:. Thanks for the explanation!
