It is much appreciated as lisp (and Emacs lisp in particular) is not the language I am most fluent in.

If so, it'd be good to cover that in test-org-table.el. calc-simplify-mode is not part of the default calc mode plist, thus adding it to the plist does not work without this change. > However, looking ahead, org-table--set-calc-mode is dropped in the last > patch.

Funny. This is also the style I prefer, but I wrote the code to conform to the style used in this context. I can fix this too. >> Subject: [PATCH 3/4] org-table: Add mode flag to enable Calc units >> simplification mode >> >> * org-table.el (org-table-eval-formula): Add the `u` mode flag to >> enable Calc's units simplification mode. > > Neat.
