Returns and Jumps

Kotlin has three structural jump expressions:

return. By default returns from the nearest enclosing function or anonymous function.
break. Terminates the nearest enclosing loop.
continue. Proceeds to the next step of the nearest enclosing loop.

All of these expressions can be used as part of larger expressions:

val s = person.name ?: return

The type of these expressions is the Nothing type.

Any expression in Kotlin may be marked with a label. Labels have the form of an identifier followed by the @ sign, for exam
