Hello! I had been recommended to post a Kotlin Thursday article here on explaining how reified generics in Kotlin improves upon the generic class-as-a-parameter pattern.  I will never be scared at looking at TornadoFX source code again! <https://link.medium.com/e7OvFkXnZV>

using clazz in ```inline fun &lt;reified T: Mammal&gt; printAnimalResultFiltered(
    list: List&lt;Mammal&gt;,
    factCheck: Mammal.() -&gt; Int
): List&lt;Mammal&gt; {
    if (list.isNotEmpty()) {
        list.forEach {
            if (clazz.isInstance(it)) println("${it.javaClass.name} - ${it.factCheck()}")
        }
    }
    return list
} ``` doesn't work

<@UEPMY9BL2> - sorry I misread, this is for reified

so `clazz.isInstance` will not apply anymore - I will fix this!

ohh this is weird - gist refuses to update

it is saved in my edit, but won't publish. I'll fix this but this is what the code should be

```inline fun &lt;reified T: Mammal&gt; printAnimalResultFiltered(
    list: List&lt;Mammal&gt;,
    factCheck: Mammal.() -&gt; Int
): List&lt;Mammal&gt; {
    if (list.isNotEmpty()) {
        list.filterIsInstance&lt;T&gt;()
            .forEach {
                println("${it.javaClass.name} - ${it.factCheck()}")
            }
    }
    return list
}

fun main() {
    println("\nSpecies count with list as param:")
    printAnimalResultFiltered&lt;Sloth&gt;(crewCrewCrew, Mammal::knownSpeciesCount)
}```

<@UEPMY9BL2> it's fixed! Thanks for the typo catch
