The SMIE grammar does not use "keywords names" but "token names".
Most tokens represent a keyword and use the same name as that keyword,
but sometimes the same keyword is mapped to different tokens depending
on context. That's what the *-forward-token and *-backward-token
functions are for.
If you look at ruby-smie--forward-token, for example, you'll see that it
can return "iuwu-mod" in the following case:
((member tok '("unless" "if" "while" "until"))
(if (save-excursion (forward-word -1) (ruby-smie--bosp))
tok "iuwu-mod"))
So I guess you can now guess what "iuwu" stands for. As for the "mod",
it stands for "statement MODifier", IIRC.
