A main() returning a void does not give the OS return value 0. Case in point:

tst.d:
void main() {}

$ dmd tst.d
(compiles)
$ tst
$ echo $?
3

I would expect 0 to be returned unless an error occured.

That's OK, then. I always thought the required return at end of main in C (or at
least gcc) redundant, since I would return 0 in almost every case. Therefore I
guess I thought the void was a replacement for the exact same behavior. But, as
you say, if I actually need the return value for something I should supply it
explicitly.
