The other, perhaps nicer, thing you can do is change the #+srcname of
the block which has the effect of changing the results block. You can do
that now. But maybe we could allow the user to over-ride the default way
in which the #+resname tag is set? E.g. by adding a :resname header
argument.
Something like this:
--8<---------------cut here---------------start------------->8---
#+srcname: test2
#+begin_src sh :resname test2-redirected
expr 2 + 3
#+end_src
#+resname: test2
: 4
#+resname: test2-redirected
: 5
--8<---------------cut here---------------end--------------->8---
Do you think that would be worthwhile?
