Too early for me to say. First reaction is that I don't see particular advantages in the :resname method over the changing the src name to justify the additional implementation effort. What I think would be useful is a way to switch all results/srcnames in a file by adding a prefix/suffix. So: #+srcname test would cause results to go to #+resname: test if org-mode-babel-source-prefix is nil, but would go to #+resname: example-test if org-mode-babel-source-prefix is "example-" and then org-mode-babel-source-prefix could be set somewhere in the headers. Maybe the #+resname which is updated could be marked with a '*' so that if somebody does C-c C-c and doesn't see an update he's reminded that the result block is not active because of a prefix. Thanks for the suggestion of changing the source block name: it goes a long way towards what I need. >> >> I've just started using org-babel in this way, so I'm not sure at >> all of what features I'll feel in the end needed.
