Hi,
Is it allowed in D similar designs?
void main() {

Yes, because writeln returns nothing, but why would you do
that? Just put the return on the next line, it's more readable.
Or, in the example above, just omit it entirely as the return
is implicit.
It's useful when writing generic wrappers, where you just want to
return whatever the wrapped function returns and don't want to
treat void functions differently.
I wouldn't use it in normal code, because it can be confusing, as
`return` usually indicates that a value is indeed returned.
