Any significant differences between lambda expressions & anonymous function in Kotlin?

Question

Kotlin has these 2 features and I think there're no significant differences between these two regardless of :

1. syntax

// lambda
val toUpper = { value: String -> 
   if (value.isEmpty()) "empty value"
   else value.toUpperCase()
}

// anonymous func
val toUpper = fun(value: String): String {
  if (value.isEmpty()) return "empty value"
  else return value.toUpperCase()
}

2. flexibility to use return statement on anonymous function

I'm still digesting these features and hope you guys can help me pass through it. Thanks.

Answer 1

Two differences according to Kotlin Reference:

1. (I think the more significant one out of the two) An anonymous function is still a function, so returning from it behaves the same as returning from any function. Returning from a lambda, however, actually returns from the function enclosing the lambda.
2. The return type of a lambda is inferred, while you can explicitly specify a return type for an anonymous function.
