This is, of course, a purely stylistic matter. But still... `main` is
special.

I know.

And it kinda makes sense to acknowledge it special nature by
not doing explicit `return 0` from `main`. `main` looks cleaner without it.

Now I'm astonished by that comment (to say the least).

I'm regularly returning status and error information to the calling
instance to act upon it. And you're saying that I should not return
any value? Or only values that are different from 0? Or only 0 if I
also return other values? - Whatever; that sounds all wrong to me.
Or is 'return' deprecated or depreciated and we should now rewrite
our source code and replace every 'return' by 'exit()', or use now
only 'exit()' in the first place instead?

I don't think you will convince me to not return 0 only because in
the special case that there's nothing specified the current language
standards defines that per default it implicitly provides that value
for me.
