and then evaluate org-calc4, which works fine. One question: Is there any way to not need the (string-to-number ...) wrapper? Another question: These names org-calc2, org-calc3, org-calc4 are not members of Emacs' "features", so where are they kept and how are they made active? Could org-mode make them globally available and not just in that buffer? I would guess we're actually doing "Library of Babel" ingestion with org-sbe?
