Agreed.  Very hacky.  I think we really need to modify the MLDS
so that it keeps the distinction, rather than trying to recreate
lost information at the ILDS level.  

That was a bigger task than I was willing to handle in my haste to
get some benchmark results for grade `il' in time to meet the BABEL'01
paper deadline, which is why I went for the hacky approach above.
I committed it on the main branch because even this hacky approach
is better than the not-working code that was there before.
But in the long term I think we should use a different approach.
