What's the deal with KFunction1<@ParameterName(name = "ctx") RoutingContext, Unit>? Is it better than (ctx: RoutingContext) -> Unit?

The second one I’ve used before, but that forces me to pass in the context as far as I can see.

router.blockingPost2("/blah", LoginController.logout(context))

The first one was generated by IntelliJ when I typed HomeController::default and alt-entered it to autocomplete the signature of the extension function.

I’m still reading up on what KFunction1 actually does, looks like reflection + magic.

Their usage must be the same AFAIK

They are certainly the same on the byte code level
