I was sure you had "black magic" to provide us with. Thanks a lot (once
again)!

I played a bit with this example. Remarks follow.

  and the small explanation.
--8<---------------cut here---------------end--------------->8---

1. On the echo functionality itself, everything is perfect, but for the
   horizontal lines that are not echo'ed.

2. For Babel, more generally, some remarks that I have for a while, but always
   forget to report (as you're allowed to consider them as "details" ;-)):

   - Babel does not find the tables if the `#+tblname: XXX' instruction is not
     located at column 0 -- annoying for me, as I try to perfectly align all
     the text and source code based on `org-indent'-like functionality;

   - the `results' block is not "naturally" aligned either;

   - less a detail than the 2 above: would it be possible to leave some text
     between the `call' and the `results': in this example, so that the
     `align' statement does not move after the table whenever we `C-c C-c' the
     block for executing the `echo'?

I think so as well. This is a must for enabling us to insert slides into a
document. And something nobody else (PowerPoint, even plain LaTeX?) can do
(AFAIK).

Best regards,
