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<FooBar>
You need to use clazz.java.isAssignableFrom(FooBar::class.java) instead.
