Given a

annotation class Foo<T>

is there a way to determine what the

T

parameter of a specific instance of the annotation obtained from reflection at runtime? Alternately, is there some variation on

annotation class Foo<T : Any>(val fooClass: KClass<T> = T::class)

which works? I'm trying to avoid having to write

@Foo<Bar>(Bar::class)

with manual duplication at use sites, but I don't see how to get at the type parameter otherwise.
