Ah, OK.  Yeah, I wonder if a good number of those features will make
it into D anytime soon.  Walter already said macros will be put off
until D3, which were one of the major things I was looking forward to
for D2..  in the mean time, a number of other ideas have come up and
have taken precedence over many things mentioned in the slides.  Some
are already implemented, though.

Better struct literals would be nice.
