Is there a way to call <https://docs.oracle.com/javase/8/docs/api/java/util/EnumSet.html#noneOf-java.lang.Class-|EnumSet.noneOf()> given only a generic type parameter, let's say T? Neither `noneOf(T::class.java)`, `noneOf(T::class)` work. If I pass around a value, then everything works fine (`noneOf(value::class.java)`), but is there a way to keep everything on the type level?

You could use a reified function:
`inline fun &lt;reified T : Enum&lt;T&gt;&gt; noneOf(): EnumSet&lt;T&gt; = EnumSet.noneOf(T::class.java)`

Thanks, figured that one in the end. But still, I'd like to use it as a class property, and there are no reified classes...

I ended up just passing an extra value to the class, no big deal, just wondered if it could be done without it

If you just care about use-site convenience  and don’t mind squinting a bit, you could have a “constructor” function for your class that’s actually `inline reified`  - if you give it the same name as the class you can use it transparently

My preference would be an `operator fun invoke` on a companion object:

<@UMXTNACBY> wow, that's pretty cute &amp; clever! didn't know I could overload the `invoke` operator :smile:. Maybe a bit too clever, but it's a small codebase, why not go wild a bit! :smile:
