I am having a difficult time distinguishing two legal lines of code: ID = expression and ID(exp1, exp2, ...) = expression I tried this rule: stat: expr NEWLINE -> expr | (ID OPENP .* CLOSEP GETS) => ID OPENP actualParameters CLOSEP GETS expr NEWLINE -> ^(INDEX ID OPENP actualParameters CLOSEP expr) | ID GETS expr NEWLINE -> ^(GETS ID expr) | NEWLINE -> ; But it says that alternatives 2 and 3 can never be matched. How do I "reactivate" 2 and 3?
