D has safeties to avoid this kind of code, because it's essentially considered a bug:
int foo() {}
void main() {
foo();
}
But this compiles with no errors:
void foo() {
return 1;
}
void main() {
foo();
}
Notice that this Java code:
class Test {
static void foo() {
return 1;
}
public static void main(String[] args) {
Test.foo();
}
}
Raises a compilation error:
Test.java:3: cannot return a value from method whose result type is void
return 1;
^
1 error
I think this avoids some mistakes.
Bye,
