Does the C target support something like @finally?  (I'm rusty on 
all these special actions, so maybe that's what @after is for, but 
at least on the face of it I can see an argument for @after being 
"after successfully matching" while @finally would be "when 
leaving the rule, successfully or not"...  not that I know whether 
that's actually the case or not :))
