Nor can I.
After a good while, I cannot figure how this works in tangle, but not execute.
The calls to `org-babel-noweb-ref-resolve' look the same, but in tangle it
returns the :noweb-ref src blocks while in execute "" is returned.
FWIW, labelling the individual src-blocks with the :noweb-ref header seems to
work.
