There are significantly different contexts: trusted files created locally and arbitrary files fetched through some link in the web. Features really convenient in the former case may became a disaster in the latter. If a user is prompted to confirm evaluation of each table formula then spreadsheet feature becomes unusable. ---- >8 ---- Enter value and press =TAB= | | Value | Result | |---+-------+--------| | # | | | #+tblfm: $3='(progn (message "%s" "pwnd") 0) ---- 8< ---- I suspect a bunch of similar problems with export feature. The ability to save an .org file as a nicely formatted PDF is great but simultaneously dangerous for files obtained from the net. I would like to have safe export, but I am afraid that actually the code would be fragile.
