** Conflict (shift/reduce) in state 21.
** Tokens involved: VAR OPER LPAREN LBRACKET INT FLOAT BOOL BEGIN
** The following explanations concentrate on token VAR.
** This state is reached from main after reading:

avg_expr OPER avg_expr

** The derivations that appear below have the following common factor:
** (The question mark symbol (?) represents the spot where the derivations begin to differ.)

main
expr SEMISEMI main
avg_expr
call
(?)

** In state 21, looking ahead at VAR, reducing production
** call -> avg_expr OPER avg_expr
** is permitted because of the following sub-derivation:

avg_expr simple_expr // lookahead token appears because simple_expr can begin with VAR
call // lookahead token is inherited
avg_expr OPER avg_expr .

** In state 21, looking ahead at VAR, shifting is permitted
** because of the following sub-derivation:

avg_expr OPER avg_expr
              call
              avg_expr simple_expr
                       . VAR
