Thank you all for working on this - this kind of thing has been on the radar for years but after Burcin left day-to-day operations around here there hasn't been the combination of energy and know-how to do this "correctly", whatever that might mean. Just keep in mind it would be nice for I in SR to be true, though I'm sure it will be since 1 in SR already is True. I do like the idea of abs(I) being an Integer and not a symbolic expression.
