Subject: Re: Bug: export aborts if ':eval query/never' in source code blocks

Eric,
As a follow-up on a related issue:
What if I want to eval a code block for some side-effect, but
*not* include code or results in export. This assumes I'm using
:session.
Is there a way to currently do that?
Setting :exports none seems to block evaluating of the code,
can the :eval argument 'override' that so the block is
eval'd, but no export is produced.
In R, I currently can just put the last line of the block
I want this behavior for as
NULL
with :exports results
and it seems to do what I want. Just wondering if there was
a more 'official' way?
Here's a sample file that seems to do as I want, with the
NULL trick. Just wonder if :eval can help at all.
* I want only the 2nd block exported
#+begin_src R :exports results :session
x <- 2 + 3
NULL
#+end_src
#+begin_src R :session :exports results
x
#+end_src
