* The script must return a list where each odd element is the "token", and each even element is the label, e.g.
[token1, label1, token2, label2]
So I need to perform extra lookups to find the token, even though the menu already had it at construction time.
Am I missing something? Or is it an incomplete implementation? (did this in H19 and 18.5)
The docs on this topic could be slightly better. Houdini scripting docs in general are superb, though!
