I quite like the "keep" idea (handy if you have a dataset containing a lot of "junk"), and I also like the idea of moving "delete" (for variables) into place under the "dataset" command. The old "delete" command could be kept as an alias, at least for a while. As for deleteobs and keepobs, these seem to me somewhat redundant given the smpl command and the ability to save the dataset.
