Thanks, Mark... I had missed that aspect entirely. I think there might be a way round it... which actually was something I had been thinking of including in the same suggestion but thought was perhaps too obscure, but now I've realized it would integrate well with it. That is to have a value-returning form of try... except... But perhaps the two of them together are too much of a change.
