it's abusing 'alias' which makes it all a mess. if we look at the code
above as 'idiomatic D code', then A and B should be similar. but if we
looking at the code as 'hacky replacement for real typedef', A and B
should not be similar.

seems that Andrei talking about 'idiomatic D' and we are talking about
'hacky typedef replacement'. that's why we can't settle the issue: we
are both right! ;-)

and that's why we need 'typedef' revived, methinks.
