This resonates with some vague ideas that keep haunting some
dark corners of my mind:

it isn't generally possible to convert "Word" [1] into Org. But what
if that "Word" is just a slight modification of something which has
been transformed from an Org document we know?

Of course, augmenting that with "pockets" where to stash 
meta-information
which might get lost on round-trip would be even more interesting. 
Perhaps
those pockets are external, tied to some (possibly change-resistant) 
hash

made of enough context.

Did I say dark corners?

[O] Bug: Table update fails for named fields [9.1.13 (release_9.1.13)]

[Piyush Srivastava]

In the current org mode version (release_9.1.13), when a named cell
formula is stored using C-u C-c =, the #+TBLFM line stores the name of
the cell without a prefix '$' sign, as in the following table (notice
that is the #+TBLFM row, there is no '$' sign before the 'sum'
variable):

|   |   c |
|---+-|
|   |   3 |
|   |  10 |
|---+-|
| # |  14 |
| ^ | sum |
|---+-|
#+TBLFM: sum=vsum(@-II$0..@-I$0)


With this storage, pressing TAB in the row after changing some entries
does not update the filed referred to by 'sum', contrary to the
description in the manual.


However, if I manually prefix a '$; to the variable 'sum' as in the
table below, then TAB update work as described in the manual (notice the
$sum variable in the #+TBLFM row):


|   |   c |
|---+-|
|   |   3 |
|   |  12 |
|---+-|
| # |  15 |
| ^ | sum |
|---+-|
#+TBLFM: $sum=vsum(@-II$0..@-I$0)


A fix is to ensure that if the LHS of a field formula being inserted
is a field name rather than a numerical reference, then a '$' is
prefixed to it.  I have the following patch with implements this:


diff --git a/lisp/org-table.el b/lisp/org-table.el

What this patch does is the following: if the reference being inserted
does not begin with an '@' or a '$', then it is assumed to be a named
reference, and a '$' is prefixed to it.  This will work *provided* no
named references themselves start with a '$'.

I am happy to assign copyright for the patch, if that is needed and if
the patch if found suitable, for it to be included in org-mode code.


Thanks,

Yes, it's apparently a feature from "org-ctags.el".

With the command above, you're not exporting the file using "ox.el".
What are you testing? Could you use a command that exports the file
(preferably using ASCII (utf-8) export back-end)?
