Hi Bastien,
I'm not sure - need to think about it some more and go back through the
manual. My initial feeling is that the example block you show should
only return "Hello!" when you request output as the reuslts and
otherwise return the return value of echo (which is the exit code in
this case).
The main problem with the additional variable you propose is that you
would only want it enabled on some source blocks and not others, so it
might need to be settable as a header option to turn it on/off for a
specific block.
