Awesome! FWIW, my needs don't require any sort of "relational" concept as some comments have suggested, I just need to be able to do all existing operations on each sheet in the workbook. I guess being able to get a list of the sheets in the workbook might be useful, as well, or get a sheet by name, but for my use case I already know the name.
