And if/then, then/else?

In think I'd agree, although I think we'll want to look at how much code
breaks in practice by not having the comma rule. We should be able to
generate warnings when the comma rule is used, though, which would
smooth a transition.
Also, this style (which I think is quite popular nowadays):
( e1
, e2
, e3)
would still work, as the layout would be closed by the comma being less
indented.
Thanks
