I find the following behavior with implicit return pretty irritating:
>>> fun calc(a: Int): Int {
... println(a)
... a * a
... }
>>> calc(3)
3
0
It would make sense to return 9 or to issue a compilation error, but this behavior doesn’t make any sense. Or do I miss something?
>>> fun calc(a: Int): Int {
... println(a)
... return a * a
... }
>>> calc(3)
3
9
With an explicit return everything is as expected.
As far as I know an implicit return is only allowed in single expression funktions, but why is it allowed in the first case then?
