extractList() fails for unnormalized i

[lawremi]

I think extractList() might need to normalize 'i' somehow, because otherwise LogicalList i, IntegerList i with subscripts < 1 and maybe other things will break it. Or the documentation needs to be clarified, because while it implies that the above cases will not work due to incompatible skeletons, it's not very obvious.

Thanks Michael. Will take a look after the release.
