Comment (by duncan):

 Though of course, existing programs use this and will break. I'm not
 saying don't do it, just bear that in mind.

 I'll have to go change every module in Gtk2Hs. :-)

 One advantage of allowing extra ','s is that it makes it easier to see
 what's really changed in a diff and it makes using #ifdefs in export lists
 easier.

 If this is going to change perhaps start by deprecating them and making it
 a warning so people will have a chance to fix their code.
