Thanks for the explanation. If I understand correctly, by default the result of evaluating the last statement is returned when no explicit return is provided, and since declaring a label is not a statement, it doesn't get evaluated. I had expected something more like the behaviour from this: 
sub fn {
  sub { 3 }
}

Where it's not the 3 that gets returned, rather it's a coderef to an anonymous subroutine.

As for 'wrong', you've guessed my meaning well. If the code is likely to mislead someone making changes at some point in the future, it is 'wrong' now. Since the 'return:' label doesn't cause the subroutine to return, putting code after it could have unexpected side-effects for anyone mistaking it for a normal 'return'.

BTW, is 'return 3;' a statement? If so, is it then a special exception to the rule 'blocks return the value of the last statement executed', or is the value of 'return 3' equal to 3 ?
