Space would be more logical as separator. Though I am wondering if people are using noweb reference names with spaces in the wild. > Feedback on the code is of course very welcome.

I'll try this soonish. I do not like the idea of using tags. What we might do is: 1. Leave :noweb-ref's current behavior of overwriting the parent parameter values. 2. Add a new :noweb-ref+ parameter to accumulate multiple noweb reference names. The relevant function to modify is `org-babel-merge-params' -- Ihor Radchenko // yantar92, Org mode contributor, Learn more about Org mode at <https://orgmode.org/>.
