| * | Prohibit using a pattern in an alternative•••When a syntax error occurs, the parser must provide a user with the names of expected tokens.
However, if a pattern appears directly in an alternative, Vartan cannot assign an appropriate name to the pattern.
Therefore, this commit prohibits alternatives from containing patterns.
