'\n'; > The range operator works differently inside a parser-rule. For example, the rule *foo*: foo : A..C ; A : 'a'; Z : 'z'; C : 'c'; will match one of the tokens A, Z or C (not one of the characters 'a', 'b' or 'c'!). Just as the `.` (DOT meta character) that has a different meaning depending in which rule it is used: it means 'any character' inside lexer rules, while it means 'any token' inside parser rules.
