[ragel-users] State Chart Finishing Actions?

[Adrian Thurston]

You should use any @0, or use @(blink,1) for the SM events. The 
priorities need to have the same name. Without a name the name of the 
machine "blinks" (with an s) is used.

Also, this will only work if the SM events are one character. I don't 
see their definitions so I'm not sure if that's the problem.
