Bug. It used to raise a hard error when you tried to add the same ivar. Now I
was cleaning up the SourceFileArray, which is used
while accessing source: so removing an ivar *needs* duplication for a short
overlap.
So I removed the hard error, which was wrong (it should have been a warning).
In Pharo3 with the new class builder this is fixed.
