if i have a variable `clazz` that is a `KClassImpl`
how would i check if that is of type `FooBar`
i tried this
`clazz.java.isInstance(FooBar::class.java)`
but that always returns false

That's not the correct method of `Class` : `isInstance` checks that the parameter is an instance of that class, which is always false for an instance of `Class&lt;FooBar&gt;`
You need to use `clazz.java.isAssignableFrom(FooBar::class.java)` instead.
