Generally allowing trailing (or leading or repeated) commas would clash
with tuple sections. Also the pair constructor "(,)" is a special case.

You could of course say that I'm using a bad style, but it remains
that it seems to be inconsistent to allow a trailing comma in one
place and not in the other. So is there an reason for this?
there is actually a bug report against the ghc package in Debian from a
user, requesting a more liberal comma separated list parsing. We did not
patch ghc in Debian to that end, though :-)
