Hello 👋
Just wondering if anyone knows how to detect whether given property is a lambda, e.g. given

class Foo(val bar: () -> Bar)
// or
class Foo(val bar: suspend () -> Bar)

how to check whether bar is actually a lambda.

I was hoping that simple KProperty.returnType is Function<*> would do the trick, sadly that returns false...

returnType is a KType, not a KClass or an instance

[ephemient]

you could do something like

returnType.isSubtypeOf(typeOf<Function<*>>())

nice that seems to do the trick
