Probably not used to seeing lambdas inside of parens:

  .get("/", ctx -> ctx.result("Hello World"))

Could also be written as

  .get("/") { ctx -> ctx.result("Hello World") }

The second form seems much more common in Kotlin.

Yeah, no, he was 100% correct, I was just looking at the wrong snippet. It's been fixed now :)
