[ragel-users] foreach character?

[Adrian Thurston]

Hey Gordon,

No worries, ragel is unique so some confusion from programmers is 
expected. You can usually answer these questions by looking at the 
precedence table in the manual. Action embedding operators bind more 
tightly than '.' and '|' and I think many programmers might find that 
strange at first.
